<div>Bithacks are optimization tricks that utilize information in bits and [https://en.wikipedia.org/wiki/Bit_manipulation bit manipulation]<br />
to accomplish their tasks. Usually they work in a slightly non-obvious way, (the most famous being the [https://en.wikipedia.org/wiki/Fast_inverse_square_root fast inverse sqrt]), and bit manipulation in general is harder on the [[65c816]]. To that end, here is a collection of some useful tricks.<br />

<div>Bithacks are optimization tricks that utilize information in bits and [https://en.wikipedia.org/wiki/Bit_manipulation bit manipulation]<br />
to accomplish their tasks. Usually they work in a slightly non-obvious way, (the most famous being the [https://en.wikipedia.org/wiki/Fast_inverse_square_root fast inverse sqrt]), and bit manipulation in general is harder on the [[65c816]]. To that end, here is a collection of some useful tricks.<br />

<div>[[File:{{#setmainimage:SMW2YI.jpg}}|300px|thumb|right|Official Artwork]]'''Super Mario World 2: Yoshi's Island''' (sometimes referred to simply as ''Yoshi's Island'') is a 2D platform game for the [[Super Nintendo]], developed by Nintendo EAD. The game is the prequel to [[Super Mario World]] and chronologically the first in the Mario franchise. The game is notable for introducing a time-based health system rather than hit points, an anomaly to what many platform games typically did in this game's time period. Rather than relying on powerful pre-rendered graphics as its contemporary, [[Donkey Kong Country]] did, '''Super Mario World 2: Yoshi's Island''' employs a very distinct, stylized arts and crafts style to stand on its own. The game makes use of the Super FX2 graphics chip (one of only four commercially-released SNES games to do so), which allows for larger, more detailed sprites and more advanced effects that emulate 3D space.<br />
<br />
== Hacking Tools ==<br />
=== Standard ===<br />
==== Golden Egg ====<br />
''Main Article: [[Golden Egg]]''<br />
<br />
'''Golden Egg''' made by Romi is the main level editor of the game, therefore the basic and essential tool. Still in beta, it allows editing objects, sprites, header settings (tileset, music, etc.), palettes, screen exits and much more.<br />
==== YI Entrance Editor ====<br />
''Main Article: [[YI Entrance Editor]]''<br />
<br />
'''YI Entrance Editor''' is a pack of 2 tools made by Romi. The first one edits the start position of Yoshi in every level, while the second one edits the midway entrances (the position where you start after you collect a midway ring in-game), both features that Golden Egg lacks. The latter is currently deprecated by [https://www.smwcentral.net/?p=section&a=details&id=14709 Raidenthequick's Better Middle Ring ASM patch].<br />
==== Ycompress ====<br />
''Main Article: [[Ycompress]]''<br />
<br />
'''Ycompress''' is a tool made by FuSoYa that decompress and dump most of the graphics in Yoshi's Island, so that they can be modified by a graphic editor. It can then be used to recompress and insert the graphics back into the ROM.<br />
==== Yoshi's Island Level Tool ====<br />
''Main Article: [[Yoshi's Island Level Tool]]''<br />
<br />
'''Yoshi's Island Level Tool''' is a tool made by FURiOUS that can be used to export and import level data and entrances from/to any rom (another lacking feature of Golden Egg). It can be also used to apply [[Asar]]'s patches.<br />
==== BTD6_maker's YI Text Editor ====<br />
''Main Article: [[BTD6_maker's YI Text Editor]]''<br />
<br />
'''BTD6_maker's YI Text Editor''' (also known as ''BYTE'') is is a text editor written in Python made by BTD6_maker, and it's used to edit various text in the game, such as level names and message boxes. The difference between this and Y.I.P.E.S. (a deprecated text editor) is that the latter may occasionally overwrite important data, which sometimes corrupt the level data.<br />
==== Sprite Set Editor ====<br />
'''Yoshi's Island Sprite Set Editor''' (also known as ''YI Sprite Set Editor'' or just ''Sprite Set Editor'') is a tool made by Kipernal that lets you edit, as the name suggests, the set of sprites used by the game, allowing you to replace existing sets with new combinations of sprites. Even being a standard tool, it has some crashing bugs and it's tedious to use because their listing system is in decimal (instead of hexadecimal).<br />
==== AddMusicY ====<br />
'''AddMusicY''' is a tool made by Jimmy which is used to insert custom music into a Yoshi's Island ROM. Due to the lack of flexibility of the YI ROM, this tool only replaces the existing songs, rather than adding new ones.<br />
<br />
=== Deprecated ===<br />
==== EggVine ====<br />
EggVine was the first editor for Yoshi's Island, and was made by Squash Monster (and later improved by Yoshis Fan). It was known for crashing a lot, and for lacking graphical display, but other than that the tool was decent and several hacks were finished by using this tool. It was obsoleted by Golden Egg.<br />
==== Y.I.P.E.S. ====<br />
'''Yoshi's Island Phrase Editing System''', usually known as ''Y.I.P.E.S.'' (or just ''YIPES'') was the first text editor for Yoshi's Island, made by Kipernal. The tool is very intuitive and has a good user interface with graphical display, but at the same time it isn't safe to use, because it may ocasionally overwrite level data. It was obsoleted by BTD6_maker's YI Text Editor.<br />
==== Title Screen Editor ====<br />
'''Yoshi's Island Title Screen Editor''' (or just ''Title Screen Editor'') is a tool made by Kipernal, which lets you edit the title screen island sprites. It's a very buggy tool (it crashes a lot and most of the time it doesn't work) and it has no practical use.<br />
=== Beta/Unfinished ===<br />
==== Pastel ====<br />
'''Pastel''' is a beta tool written in Python 2.7 by Lui37, that can be used to edit the palette sets in the game. Despite being useful, it has at least [https://smwc.me/1446056 one crashing bug] that corrupts the rom, and one that crashes the tool.<br />
==== Overworld Editor ====<br />
'''Yoshi's Island Overworld Editor''' (or just ''Overworld Editor'') is a beta tool made by tehaxor69 which lets you edit the tilemaps and sprites of the overworld (the level selection screen, specifically). Despite the tilemap editing works, the tool is unfinished and unpolished so it's hard to use (bad user interface and functions and lack of core features).<br />
==== Golden EggVine ====<br />
'''Golden EggVine''' is a unfinished level editor, started by Yoshis Fan and default0. It's presumable it was going to be a kind of blend of Golden Egg and EggVine.<br />
==== YoshiOmelette ====<br />
'''YoshiOmelette''' is a unfinished level editor, started by shibbo.<br />

==== WRAM ====<br />
The Super Nintendo Entertainment System has 128kb of system RAM (aka WRAM) that every game can access, spanning from $7E0000~$7FFFFF. [https://github.com/Raidenthequick/yoshisisland-disassembly/wiki/WRAM-Map This map] explains what each address represents in Yoshi's Island mostly in standard gameplay gamemode $0F. In Yoshi's Island in particular, since it has the Super FX enhancement chip, much of the game's memory is stored in cartridge RAM instead. This is why there is so much free WRAM in this game. Nonetheless, there are still some pretty important pieces of data stored here.<br />
==== CARTRAM/SRAM ====<br />
Yoshi's Island has 32KB of Save RAM, spanning from $700000~$707FFF. [https://github.com/Raidenthequick/yoshisisland-disassembly/wiki/SRAM-Map This map] explains what each address represents in standard gameplay gamemode $0F. The reason so much important stuff is stored here is because the Super FX can only access cartridge RAM, not SNES system RAM. Note that other gamemodes may use these addresses for completely different purposes.<br />

<div>Bithacks are optimization tricks that utilize information in bits and [https://en.wikipedia.org/wiki/Bit_manipulation bit manipulation]<br />
to accomplish their tasks. Usually they work in a slightly non-obvious way, (the most famous being the [https://en.wikipedia.org/wiki/Fast_inverse_square_root fast inverse sqrt]), and bit manipulation in general is harder on the 65c816. To that end here is a collection of some useful tricks.<br />

to accomplish their tasks. Usually they work in a slightly non-obvious way, (the most famous being the [https://en.wikipedia.org/wiki/Fast_inverse_square_root fast inverse sqrt]), and bit manipulation in general is harder on the 65c816. To that end here is a collection of some useful tricks.<br />

<div>Bithacks are optimization tricks that utilize information in bits and [https://en.wikipedia.org/wiki/Bit_manipulation bit manipulation]<br />
to accomplish their tasks. Usually they work in a slightly non-obvious way, (the most famous being the [https://en.wikipedia.org/wiki/Fast_inverse_square_root fast inverse sqrt]), and bit manipulation in general is harder on the 65c816. To that end here is a collection of some useful tricks.<br />

<hr />
<div>{{DISPLAYTITLE:LC_LZ2}}<br />
LZ2 or LC_LZ2, as named by [[Lunar Compress]], is a lossless data compression format, used by [[Super Mario World]] to compress graphics. It is also used by [[Super Mario World 2: Yoshi's Island]].<br />
<br />
== Compression ==<br />
<br />
The compressed data consists of "chunks", each with a header:<br />
<br />
<pre><br />
bits<br />
76543210<br />
CCCLLLLL<br />
<br />
CCC: Command bits<br />
LLLLL: Length<br />
</pre><br />
<br />
If the header byte is $FF, the end of the compressed data has been reached, and decompression will be aborted.<br />
<br />
Here is a list of commands bits which the LC_LZ2 decompression function can use during the decompression:<br />
<br />
<pre><br />
000 "Direct Copy"<br />
Followed by (L+1) bytes of data<br />
001 "Byte Fill"<br />
Followed by one byte to be repeated (L+1) times<br />
010 "Word Fill"<br />
Followed by two bytes. Output first byte, then second, then first,<br />
then second, etc. until (L+1) bytes has been outputted<br />
011 "Increasing Fill"<br />
Followed by one byte to be repeated (L+1) times, but the byte is<br />
increased by 1 after each write<br />
100 "Repeat"<br />
Followed by two bytes (big endian byte order) containing address (in the<br />
output buffer) to copy (L+1) bytes from<br />
101 (Unused command)<br />
110 (Unused command)<br />
111 "Long length"<br />
This command has got a two-byte header:<br />
111CCCLL LLLLLLLL<br />
CCC: Real command<br />
LLLLLLLLLL: Length<br />
</pre><br />
<br />
== Decompression ==<br />
<br />
During the decompression, the decompressed chunks are outputted into a buffer which is either RAM or SRAM. SMW uses the RAM address $7E:AD00 as its decompression buffer.<br />
<br />
== Usage ==<br />
<br />
You can use the LC_LZ2 compression to mainly compress graphics. Technically you can compress anything with this format, but graphics is preferred due to their big size. Seeing the SNES isn't fast, the decompression takes a while to finish, so whenever you overuse the compression the loading time will increase.<br />
<br />
== Other ==<br />

<hr />
<div>The '''SNES''' utilizes '''indirect color indexing''' to have multiple graphics storing formats available in its architecture: 2bpp, 3bpp, 4bpp, 8bpp and Mode 7. with 2 and 4bpp being the most commonly used.<br />
<br />
== Primer on Indirect Color Indexing ==<br />
'''Indexed color''' is a technique to manage digital images' colors in a limited fashion, in order to save computer memory and file storage, while speeding up display refresh and file transfers.<br />
<br />
When an image is encoded in this way, color information is not directly carried by the image pixel data, but is stored in a separate piece of data called a '''palette''': an array of color elements. Every element in the array represents a color, indexed by its position within the array. The individual entries are sometimes known as '''color registers'''. The image pixels do not contain the full specification of its color, but only its index in the ''palette''. This technique is sometimes referred as '''pseudocolor''' or '''indirect color''', as colors are addressed indirectly.<br />
<br />
== How It Works ==<br />
Let's take a 1bpp sprite, one of the invaders of Space Invaders by Taito, for example.<br />
[[File:saa03 1bpp.png|frame|center|Credit of picture to georgjz of [https://georgjz.github.io/snesaa03/ Machine Code Construction Yard].]]<br />
<br />
Using binary, '''the pixels index themselves to a palette color'''. 0 to white, 1 to black. The picture itself is compressed by turning it to binary which is then converted to hex to store in data (11000 of the tip of the head translating to $18, for one).<br />
<br />
However, once 2bpp or higher are introduced, bitplanes come along with them.<br />
<br />
For instance, take the sprite of Link in Legend of Zelda for the Nintendo Entertainment System.<br />
[[File:saa03 2bpp.png|frame|center|Credit of picture to georgjz of [https://georgjz.github.io/snesaa03/ Machine Code Construction Yard].]]<br />
<br />
As it is 2bpp (literally two bits per pixel), two bitplanes are used to account for the increase in color (as $03 = #04 = %00000011). Essentially, each byte represents a row, and to get the color index, we have to combine the two. 0 and 0 = transparent in the SNES' case, 0 and 1 = green, so on and so forth.<br />
<br />
For 3, 4bpp, the conversion is rather obvious. But the most commonly used are 2 and 4bpp. As an aside, '''SNES tiles are stored in 8x8'''.<br />
<br />
== Data Storage ==<br />
Due to the ability to swap bits-per-pixel formats, the SNES has the ability to use a mix of Planar and Intertwined data storage, using Planar in Mode 7.<br />
<br />
* '''Planar''': Each row (i.e., byte) of a bitplane is stored consecutively, starting with the top row of the lowest bitplane; then the same is repeated with each row of the next bitplane.<br />
* '''Intertwined''': Each pair of bytes consecutively stored represents a row of the sprite with the byte from the lower bitplane being stored first.<br />
<br />
In the SNES, the first two planes of an 8x8 tile are always stored first, and once all those are done, the third and fourth get stored.<br />
<br />

<br />
== Formats ==<br />
=== 2bpp ===<br />
'''Colors Per Tile''': 0-3<br><br />
'''Space Used''': 2 bits per pixel. 16 bytes per 8x8 tile.<br />
<br />
Note: This is a tiled, planar bitmap format. Each pair represents one byte.<br><br />
Format:<br />
[r0, bp1], [r0, bp2], [r1, bp1], [r1, bp2], [r2, bp1], [r2, bp2], [r3, bp1], [r3, bp2]<br />
[r4, bp1], [r4, bp2], [r5, bp1], [r5, bp2], [r6, bp1], [r6, bp2], [r7, bp1], [r7, bp2]<br />
<br />
Short Description:<br />
Bitplanes 1 and 2 are intertwined row by row.<br />
<br />
=== 3bpp ===<br />
'''Colors Per Tile''': 0-7<br><br />
'''Space Used''': 3 bits per pixel. 24 bytes for a 8x8 tile.<br />
<br />
Note: This is a tiled, planar bitmap format. Each pair represents one byte.<br><br />
Format:<br />
[r0, bp1], [r0, bp2], [r1, bp1], [r1, bp2], [r2, bp1], [r2, bp2], [r3, bp1], [r3, bp2]<br />
[r4, bp1], [r4, bp2], [r5, bp1], [r5, bp2], [r6, bp1], [r6, bp2], [r7, bp1], [r7, bp2]<br />
[r0, bp3], [r1, bp3], [r2, bp3], [r3, bp3], [r4, bp3], [r5, bp3], [r6, bp3], [r7, bp3]<br />
<br />
Short Description:<br />
Bitplanes 1 and 2 are stored first, intertwined row by row. Then the third bitplane is stored row by row. <br><br />
This format isn't used by many games since it's actually a type of compression, because the SNES doesn't natively support the 3BPP format. There is a routine that inserts the fourth bitplane before or while it's being transferred to VRAM so that it can be used by the SNES.<br />
<br />
=== 4bpp ===<br />
'''Colors Per Tile''': 0-15<br><br />
'''Space Used''': 4 bits per pixel. 32 bytes for a 8x8 tile.<br />
<br />
Note: This is a tiled, planar bitmap format. Each pair represents one byte<br><br />
Format:<br />
[r0, bp1], [r0, bp2], [r1, bp1], [r1, bp2], [r2, bp1], [r2, bp2], [r3, bp1], [r3, bp2]<br />
[r4, bp1], [r4, bp2], [r5, bp1], [r5, bp2], [r6, bp1], [r6, bp2], [r7, bp1], [r7, bp2]<br />

[r4, bp3], [r4, bp4], [r5, bp3], [r5, bp4], [r6, bp3], [r6, bp4], [r7, bp3], [r7, bp4]<br />
<br />
Short Description:<br />
Bitplanes 1 and 2 are stored first, intertwined row by row. Then bitplanes 3 and 4 are stored, intertwined row by row.<br />
<br />
=== 8bpp ===<br />
'''Colors Per Tile''': 0-255<br><br />
'''Space Used''': 8 bits per pixel. 64 bytes for a 8x8 tile.<br />
<br />
Note: This is a tiled, planar bitmap format. Each pair represents one byte<br><br />
Format:<br />
[r0, bp1], [r0, bp2], [r1, bp1], [r1, bp2], [r2, bp1], [r2, bp2], [r3, bp1], [r3, bp2]<br />
[r4, bp1], [r4, bp2], [r5, bp1], [r5, bp2], [r6, bp1], [r6, bp2], [r7, bp1], [r7, bp2]<br />
[r0, bp3], [r0, bp4], [r1, bp3], [r1, bp4], [r2, bp3], [r2, bp4], [r3, bp3], [r3, bp4]<br />
[r4, bp3], [r4, bp4], [r5, bp3], [r5, bp4], [r6, bp3], [r6, bp4], [r7, bp3], [r7, bp4]<br />
[r0, bp5], [r0, bp6], [r1, bp5], [r1, bp6], [r2, bp5], [r2, bp6], [r3, bp5], [r3, bp6]<br />
[r4, bp5], [r4, bp6], [r5, bp5], [r5, bp6], [r6, bp5], [r6, bp6], [r7, bp5], [r7, bp6]<br />
[r0, bp7], [r0, bp8], [r1, bp7], [r1, bp8], [r2, bp7], [r2, bp8], [r3, bp7], [r3, bp8]<br />
[r4, bp7], [r4, bp8], [r5, bp7], [r5, bp8], [r6, bp7], [r6, bp8], [r7, bp7], [r7, bp8]<br />
<br />
Short Description:<br />
Bitplanes 1 and 2 are stored first, intertwined row by row. Bitplanes 3 and 4 are stored next intertwined row by row. Then Bitplanes 5 and 6 intertwined row by row. Finally, Bitplanes 7 and 8 are stored intertwined row by row.<br />
<br />
Alternatively and equivalently: In a normal paletted 8x8 image, the bits of pixel data are accessed with byte index yyyxxx and bit index ccc. In SNES 8bpp, the indices are instead ccyyyc xxx.<br />
<br />
=== Mode 7 ===<br />
'''Colors Per Tile''': 0-255<br><br />
'''Space used''': 8 bits per pixel. 64 bytes for a 8x8 tile.<br />
<br />
Note: This is a tiled, linear bitmap format. Each pair represents 1 byte.<br><br />
Format:<br />
[p0 r0: bp!], [p1 r0: bp!], [p2 r0: bp!], [p3 r0: bp!]<br />
[p4 r0: bp!], [p5 r0: bp!], [p6 r0: bp!], [p7 r0: bp!]<br />
[p0 r1: bp!], [p1 r1: bp!], [p2 r1: bp!], [p3 r1: bp!]<br />
[p4 r1: bp!], [p5 r1: bp!], [p6 r1: bp!], [p7 r1: bp!]<br />
...<br />
[p0 r7: bp!], [p1 r7: bp!], [p2 r7: bp!], [p3 r7: bp!]<br />
[p4 r7: bp!], [p5 r7: bp!], [p6 r7: bp!], [p7 r7: bp!]<br />
<br />
Short Description:<br />
Each pixel has its bitplanes stored right after another, so each byte directly references a palette color without needing to "combine" the bitplanes.<br />
<br />
== Palette format ==<br />
The SNES uses a format known as BGR555, rather similar to RGB888. The conversion method is simple, take the five most significant bytes of each color component, and place them backwards (Blue, Green, Red), setting the most significant bit to 0.<br />
<br />
[[File:saa03 palette01.png|frame|center|Credit of picture to georgjz of [https://georgjz.github.io/snesaa03/ Machine Code Construction Yard].]]<br />
<br />
This gives the SNES the ability to use any color that fits in that spectrum rather than stick to fixed palettes set by the machine.<br />

<hr />
<div>All [[SNES]] gamepaks have an internal header that is used to identifying the game, producer, region and technical aspects of the ROM. It's often referred as '''Internal ROM Header''' or '''SNES Software Specification'''.<br />
<br />
Although it's not required to run a game on real hardware, the SNES ROM Header was used during the Nintendo approval process for validation and it's also used by the SNES emulators to identify and determine the memory layout and ROM type.<br />
<br />
The data starts at SNES address $00:FFB0 and ends at $00:FFDF. $00:FFE0 though $00:FFFF contains the SNES vector information and '''it's actually used''' by the SNES CPU to determine where to execute when an interrupt occurs.<br />

== Data Name Types ==<br />
<br />
=== Maker Code ===<br />
Two alphanumeric ASCII bytes identifying your company. Ignored by emulators; for ROM hackers and homebrewers, just insert whatever.<br />
=== Game Code ===<br />
Four alphanumeric ASCII bytes identifying your game. Ignored by emulators; for ROM hackers and homebrewers, just insert whatever.<br />
<br />
Exception: If the game code starts with Z and ends with J, it's a BS-X flash cartridge.<br />
=== Fixed Value ===<br />
The fixed value bytes at $00FFB6-$00FFBC should be #$00. The fixed value byte at $00FFDA should be #$33.<br />
=== Expansion RAM Size ===<br />
Should be #$00 for most roms. For the exception, see RAM Size.<br />
=== Special Version ===<br />
Should be #$00.<br />
=== Game Title Specification ===<br />
The game title is 21 bytes long, encoded with the [https://en.wikipedia.org/wiki/JIS_X_0201 JIS X 0201] character set (which consists of standard ASCII plus katakana). If the title is shorter than 21 bytes, then the remainder should be padded with spaces (0x20).<br />
<br />
=== Cartridge Configuration ===<br />
==== Map Mode ====<br />
Common values: #$20 - 2.68MHz LoROM, #$21 - 2.68MHz HiROM, #$23 - SA-1; #$25 - 2.68MHz ExHiROM; #$30 - 3.58MHz LoROM, #$31 - 3.58MHz HiROM; #$35 - 3.58MHz ExHiROM<br />
==== Cartridge Type ====<br />
Common values: #$00 - ROM only; #$01 - ROM and RAM; #$02 - ROM, RAM and battery; #$33 - ROM and SA-1; #$34 - ROM, SA-1 and RAM; #$35 - ROM, SA-1, RAM and battery<br />
===== Sub-Number =====<br />
==== ROM Size ====<br />
2^(this value) would be the size of the ROM in kilobytes. For example, for 512KB, this should be #$09.<br />
<br />
==== RAM Size ====<br />
2^(this value) would be the size of the SRAM (if present) in kilobytes. Maximum supported value is #$07.<br />
<br />
Exception: If you're using SuperFX aka GSU-1, move this value to the Expansion RAM Size field, and put #$00 in this byte.<br />
<br />
=== Destination Code ===<br />
Where the game is intended to be sold. Common values: #$00 - Japan; #$01 - USA; #$02 - Europe (enables 50fps PAL mode)<br />
=== Mask ROM Version ===<br />
Should be #$00, or increased every time you release a new ROM version.<br />
<br />
=== ROM Verification ===<br />
==== Complement Check ====<br />
This is the 16-bit complement (bit-inverse) of the checksum. This is used so that the checksum value cancels itself out when calculating the real checksum.<br />
==== Check Sum ====<br />
This is simply the 16-bit sum of all bytes in the ROM. For power-of-2-sized ROMs, no mirroring is used, each byte of ROM is counted exactly once.<br />
<br />
For non-power-of-2-sized ROMs (e.g. 2.5MB or 6MB), first the checksum for the largest power-of-2 area smaller than the ROM size (so 4MB for 6MB ROMs, 2MB for 2.5MB ROMs) is computed normally. Then the remaining part is repeated until it's the same size as the first part (so the last 2MB of a 6MB ROM is repeated once so both halves are 4MB, and the last 512KB of a 2.5MB ROM is repeated 4 times so both halves are 2MB). Then its checksum is computed and the checksums of the 2 halves are added to get the final checksum.<br />
<br />
== CPU Exception Vectors ==<br />
<br />
The vectors from $00:FFE0-$00:FFEF are used when the SNES is running in native mode, while the vectors from $00:FFF0-$00:FFFF are used when the SNES is running in emulation mode. Note that ABORT is technically unused, but listed for completion.<br />
<br />
Also note that the vectors are only 16 bits wide, so they can only jump to addresses within bank $00. If you want to jump to a different bank, or you need FastROM addressing, point them to a JML instruction. With WRAM being mapped at $0000-$1FFF on bank $00, it's possible to point them on that range, being an interesting option for run-time code modification.<br />
<br />
Certain enhancement chips like [[SA-1]] and [[Super FX]] can override the CPU vectors on special occasions.<br />

=== Expansion RAM Size ===<br />
Common values: #$00 - none, #$01 - 2KB, #$03 - 8KB, #$05 - 32KB, #$06 - 64KB, #$07 - 128KB<br />
=== Special Version ===<br />
Should be #$00.<br />
=== Game Title Specification ===<br />
The game title is 21 bytes long, encoded with the [https://en.wikipedia.org/wiki/JIS_X_0201 JIS X 0201] character set (which consists of standard ASCII plus katakana). If the title is shorter than 21 bytes, then the remainder should be padded with spaces (0x20).<br />
<br />
=== Cartridge Configuration ===<br />
==== Map Mode ====<br />
Common values: #$20 - 2.68MHz LoROM, #$21 - 2.68MHz HiROM, #$23 - SA-1; #$25 - 2.68MHz ExHiROM; #$30 - 3.58MHz LoROM, #$31 - 3.58MHz HiROM; #$35 - 3.58MHz ExHiROM<br />
==== Cartridge Type ====<br />
Common values: #$00 - ROM only; #$01 - ROM and RAM; #$02 - ROM, RAM and battery; #$33 - ROM and SA-1; #$34 - ROM, SA-1 and RAM; #$35 - ROM, SA-1, RAM and battery<br />
===== Sub-Number =====<br />
==== ROM Size ====<br />
2^(this value) would be the size of the ROM in kilobytes. For example, for 512KB, this should be #$09.<br />
<br />
==== RAM Size ====<br />
2^(this value) would be the size of the SRAM (if present) in kilobytes. Maximum supported value is #$07.<br />
<br />
=== Destination Code ===<br />
Where the game is intended to be sold. Common values: #$00 - Japan; #$01 - USA; #$02 - Europe (enables 50fps PAL mode)<br />
=== Mask ROM Version ===<br />
=== ROM Verification ===<br />
==== Complement Check ====<br />
This is the 16-bit complement (bit-inverse) of the checksum. This is used so that the checksum value cancels itself out when calculating the real checksum.<br />
==== Check Sum ====<br />
This is simply the 16-bit sum of all bytes in the ROM. For power-of-2-sized ROMs, no mirroring is used, each byte of ROM is counted exactly once.<br />
<br />
For non-power-of-2-sized ROMs (e.g. 2.5MB or 6MB), first the checksum for the largest power-of-2 area smaller than the ROM size (so 4MB for 6MB ROMs, 2MB for 2.5MB ROMs) is computed normally. Then the remaining part is repeated until it's the same size as the first part (so the last 2MB of a 6MB ROM is repeated once so both halves are 4MB, and the last 512KB of a 2.5MB ROM is repeated 4 times so both halves are 2MB). Then its checksum is computed and the checksums of the 2 halves are added to get the final checksum.<br />
<br />
== CPU Exception Vectors ==<br />
<br />
The vectors from $00:FFE0-$00:FFEF are used when the SNES is running in native mode, while the vectors from $00:FFF0-$00:FFFF are used when the SNES is running in emulation mode. Note that ABORT is technically unused, but listed for completion.<br />
<br />
Also note that the vectors are only 16 bits wide, so they can only jump to addresses within bank $00. If you want to jump to a different bank, or you need FastROM addressing, point them to a JML instruction. With WRAM being mapped at $0000-$1FFF on bank $00, it's possible to point them on that range, being an interesting option for run-time code modification.<br />
<br />
Certain enhancement chips like [[SA-1]] and [[Super FX]] can override the CPU vectors on special occasions.<br />

<div>Bithacks are optimization tricks that utilize information in bits and [https://en.wikipedia.org/wiki/Bit_manipulation bit manipulation]<br />
to accomplish their tasks. Usually they work in a slightly non-obvious way, (the most famous being the [https://en.wikipedia.org/wiki/Fast_inverse_square_root fast inverse sqrt]), and bit manipulation in general is harder on the 65c816. To that end here is a collection of some useful tricks.<br />

<div>{{DISPLAYTITLE:LC_LZ2}}<br />
LZ2 or LC_LZ2, as named by [[Lunar Compress]], is a lossless data compression format, used by [[Super Mario World]] to compress graphics. It is also used by [[A Link to the Past]] and [[Super Mario World 2: Yoshi's Island]].<br />
<br />
== Compression ==<br />
<br />
The compressed data consists of "chunks", each with a header:<br />
<br />
<pre><br />
bits<br />
76543210<br />
CCCLLLLL<br />
<br />
CCC: Command bits<br />
LLLLL: Length<br />
</pre><br />
<br />
If the header byte is $FF, the end of the compressed data has been reached, and decompression will be aborted.<br />
<br />
Here is a list of commands bits which the LC_LZ2 decompression function can use during the decompression:<br />
<br />
<pre><br />
000 "Direct Copy"<br />
Followed by (L+1) bytes of data<br />
001 "Byte Fill"<br />
Followed by one byte to be repeated (L+1) times<br />
010 "Word Fill"<br />
Followed by two bytes. Output first byte, then second, then first,<br />
then second, etc. until (L+1) bytes has been outputted<br />
011 "Increasing Fill"<br />
Followed by one byte to be repeated (L+1) times, but the byte is<br />
increased by 1 after each write<br />
100 "Repeat"<br />
Followed by two bytes (ABCD byte order) containing address (in the<br />
output buffer) to copy (L+1) bytes from<br />
101 (Unused command)<br />
110 (Unused command)<br />
111 "Long length"<br />
This command has got a two-byte header:<br />
111CCCLL LLLLLLLL<br />
CCC: Real command<br />
LLLLLLLLLL: Length<br />
</pre><br />
<br />
== Decompression ==<br />
<br />
During the decompression, the decompressed chunks are outputted into a buffer which is either RAM or SRAM. SMW uses the RAM address $7E:AD00 as its decompression buffer.<br />
<br />
== Usage ==<br />
<br />
You can use the LC_LZ2 compression to mainly compress graphics. Technically you can compress anything with this format, but graphics is preferred due to their big size. Seeing the SNES isn't fast, the decompression takes a while to finish, so whenever you overuse the compression the loading time will increase.<br />
<br />
== Other ==<br />
<br />
You can see an LC_LZ2 decompression routine setup at SNES $00:B888. The decompression routine itself is located at SNES $00:B8DE.<br />

<hr />
<div>Here is a RAM Map for F-Zero that aims to be fairly comprehensible.<br />
<br />
__TOC__<br />
<br />
===== Data Types =====<br />
{| class="wikitable"<br />
|-<br />
! Name !! Accepted Values !! Size !! Description<br />
|-<br />
| Angle16 || 0x0000 - 0xBFFF || 16-bit || An angle with extra fractional precision.<br><br />
0x0000 = 0 degrees<br><br />
0xBFFF ≃ 359.992675781 degrees<br><br />
Only the high byte affects the gameplay, the low byte is there just for fractional precision.<br><br />
(Each unit increments the real angle value by about 0.00732421875 degrees)<br />
|-<br />
| Angle8 || 0x00 - 0xBF || 8-bit || An angle without the fractional precision.<br><br />
0x00 = 0 degrees<br><br />
0xBF ≃ 358.125 degrees<br><br />
(Each unit increments the real angle value by about 1.875 degrees)<br />
|-<br />
| CoordX || 0x0000 - 0x1FFF || 16-bit || X coordinate value. These usually wrap around at 0x1FFF automatically.<br />
|-<br />
| CoordY || 0x0000 - 0x0FFF || 16-bit || Y coordinate value. These usually wrap around at 0x0FFF automatically.<br />
|}<br />
<br><br />
===== Zero Page (Direct Page) =====<br />
The Direct Page register (DP) is fixed to #$0000 all the time.<br />
{| class="wikitable"<br />
|-<br />
! Address !! Length !! Type !! Description<br />
|-<br />
| $7E0000 || ?? bytes || Misc. || Scratchpad RAM. Used for various purposes, including: temporary storage, subroutine parameters, etc.<br />
|-<br />
| $7E0034 || 1 byte || Sprites || Used in the AI car graphics routine.<br><br />
How many sprite tiles were needed to draw the AI car.<br><br />
Stored to $7E11D0 when the graphics routine ends.<br />
|-<br />
| $7E003E || 2 bytes || Misc. || Relevant value picked from the table at 7E:1076.<br />
|-<br />
| $7E0040 || 1 byte || Flag || "Frame done" flag. Set to zero at the start of the main loop.<br><br />
When NMI happens, it's decremented to #$FF, unless the value was already non-zero (i.e. a lag frame occurred.)<br><br />
This is used to make sure the gamestate runs once per frame.<br />
|-<br />
| $7E0041 || 2 bytes || Pointer || IRQ code pointer.<br><br />
$8612 - Do nothing;<br><br />
$8616 (V-Counter = 18) - Set transparent power bar color, then trigger next IRQ at V-Counter = 28, set IRQ code pointer $863C;<br><br />
$863C (V-Counter = 28) - Set "horizon fog" color math settings, then trigger next IRQ at V-Counter = 47, set IRQ code pointer $865A;<br><br />
$865A (V-Counter = 47) - Set BG mode to 7, then trigger next IRQ at V-Counter = 86, set IRQ code pointer $8673;<br><br />
$8673 (V-Counter = 86) - Set player's shadow/finished rank color, then set the IRQ code pointer to $8612;<br><br />
$8691 (V-Counter = $7E0043) - Set BG mode to 7, then set the IRQ code pointer to $8612.<br />
|-<br />
| $7E0043 || 2 bytes || IRQ || Scanline where the Mode7 BG starts. Used only for IRQ pointer $8691, on the race intro sequence.<br />
|-<br />
| $7E0045 || 1 byte || Flag || When the MSB is set, sound effects won't play. This is used to keep playing the "player wreckage" sounds when $7E0048 >= #$80.<br />
|-<br />
| $7E0046 || 4 bytes || I/O || SPC700 I/O ports. Various values can be written to play music or sound effects.<br />
|-<br />
| $7E004A || 1 byte || Misc. || Number of cars currently on screen, multiplied by two. (A bit of a mystery still, but seems to be used in a loop that assigns sprite priorities based on their Y position)<br />
|-<br />
| $7E004B || 2 bytes || Sprites || Index to OAM Table #1 ($7E0200) for routines that print characters/strings on screen.<br />
|-<br />
| $7E004D || 1 byte || Sprites || Index to OAM Table #2 ($7E0420) for routines that print characters/strings on screen.<br />
|-<br />
| $7E004E || 1 byte || Sprites || Used for bit-fiddling on OAM Table #2. Used in conjunction with $7E004D.<br />
|-<br />
| $7E004F || 1 byte || Hardware mirror || Mirror of SNES register $2101.<br />
|-<br />
| $7E0050 || 1 byte || Flag || "Is the game drawing cars" flag. Non-zero = Yes.<br><br />
This is used to correctly handle OAM DMA.<br />
|-<br />
| $7E0051 || 1 byte || Counter || "Global" frame counter. Always increments every frame (except lag frames), no matter what.<br><br />
See also: $7E009A ("in-race" frame counter)<br />
|-<br />
| $7E0052 || 1 byte || Misc. || Player car type.<br><br />
&#x23;$00 = Blue Falcon; #$01 = Wild Goose; #$02 = Golden Fox; #$03 = Fire Stingray.<br />
|-<br />
| $7E0053 || 1 byte || Misc. || Current race number.<br><br />
From #$00 to #$04 in Grand Prix mode.<br><br />
From #$00 to #$06 in Practice mode.<br />
|-<br />
| $7E0054 || 3 bytes || Misc. || Current gamestate (game mode).<br><br />
The first byte is the "main" gamestate, the second byte is the "sub" gamestate and the third byte is the "sub-sub" gamestate.<br><br />
This gamestate stuff is a complicated subject, which I plan to explain in more detail later.<br />
|-<br />
| $7E0057 || 1 byte || Misc. || Current difficulty setting.<br><br />
&#x23;$00 = Beginner; #$01 = Standard; #$02 = Expert/Master (for Master, the flag at $7E0F3D is set)<br />

&#x23;$00 = Player is in control; Other = Pre-recorded race is running.<br />
|-<br />
| $7E005C || 1 byte || Flag || A flag related to color math effects.<br><br />

|-<br />
| $7E0093 || 1 byte || Flag || Mode7 tilemap update flag. #$00 = don't update; #$01 = update only horizontally; Other = update both horizontally and vertically<br />

|-<br />
| $7E009F || 1 byte || Misc. || Amount of VRAM DMA transfers to perform for the next frame. Used for the $7E0420 DMA queue.<br><br />
This is a bit different from $7E0092, due to the fact that the $7E0420 DMA queue can be interpreted in two different ways.<br><br />
When the MSB clear, the DMA queue is interpreted normally (same functionality as the $7E0AE0 DMA queue, but structured differently.)<br><br />
When the MSB is set, the DMA queue is interpreted as a "fill with byte," and each entry in the DMA queue occupies four bytes.<br><br />

<hr />
<div>Organization comes later. Feel free to add major patches here as well.<br><br />
Also feel free to suggest a good way to represent SA-1 addresses (if applicable).<br />
<br />
== Lunar Magic ==<br />
Note about SA-1:<br />
<br />
For addresses between $7E:0000-$7E:00FF, the SA-1 equivalent is $3000-$30FF (code bank). For addresses between $7E:0200-$7E:1FFF, the SA-1 equivalent is $6200-$7FFF (code bank) or $40:0200-$40:1FFF (absolute).<br />
<br />
Any other address used by Lunar Magic does not have any SA-1 equivalent and must be manipulated by the SNES CPU. <br />
<br />
=== RAM ===<br />
Most of these addresses were acquired from Lunar Magic's help file and files floating around the internet.<br />

* t: Two layers flag. If set, it means the level has two interactive layers (layer 1+2 or layer 1+3).<br />
* P: New sprite spawn flag. It's a copy of the 5th bit from the sprite header and it's used for checking if the sprites uses the new data structure or not.<br />

| $7E1DFA || 0x1 || Command list.<br><br />
*$01 - Jump SFX. Sounds glitched due to it overwritting part of arpeggio's RAM with unexpected data. See L_0A14 for more details.<br><br />
*$02 - Turns on Yoshi Drums.<br><br />
*$03 - Turns off Yoshi Drums.<br><br />
*$04 - Grinder SFX. Potentially glitched.<br><br />

* To write to ARAM: Set $7FB002 to the address, and $7FB004 to the value to write. Note that the address cannot be $FFxx.<br />
* To write to the S-DSP: Set $7FB002 to the address, $7FB003 to #$FF, and $7FB004 to the value to write.<br />
|-<br />
| $7FB004 || 0x4 || SPC Output.<br><br />
* $F4 $05 will reset $7FB004 and $7FB005.<br><br />
* $F9 $XX $YY will send $XX and $YY to $7FB004 and $7FB005 respectively. (Needs verification)<br><br />
* $7FB006 and $7FB007 are unused and most likely have garbage sent by the program.<br />

This is an ever-so-slightly modified version of SMW's SPC upload routine. You can jump here at any time to upload data to the SPC.<br><br />
Input:<br><br />
* $00-$02 - Address of the block to upload to ARAM<br><br />
* $03-$04 - Position in ARAM to jump to upon completion<br><br />
* $05-$06 - Clobbered. Unused on entry; will be the size of the transferred data when finished.<br><br />
|-<br />
| $008135 || UploadSPCDataDynamic. This address needs to be checked.<br />
This is an alternate version of the upload routine. Call this if it is impossible to determine ahead of time where data will go. This routine is used to upload samples by default, but it can upload anything.<br><br />
Input:<br><br />
* $00-$02 - Address of the block to upload to ARAM<br><br />
* $03-$04 - Position in ARAM to jump to upon completion<br><br />
* $05-$06 - Size of the data to upload (this address is NOT clobbered).<br><br />
* $07-$08 - Address in ARAM to upload to (recommended to increment it by ($05) when you finish to upload consecutive data)<br><br />

Power Mario Contest was the 2019 Super Mario World Hacking contest where anyone can use any resources to make a level, similar to SMW Central's "Chocolate Level Design Contest". While only 7 people competed, the effort each entry provides serves as a reminder of why people hack [[Super_Mario_World|Super Mario World]] in the first place. <br />
