Anyways I believe the data files are encrypted.



I've uploaded what is probably the file table.

Here's some headers for the files: http://www.mediafire.com/download/kuyc8 ... /data2.zip

here is the xor key

Code: Select all

FF FE FD FC 0F 1F 2F

LOl this is a mugen file

Here is the bms for these files.

Code: Select all

The character sprites are swizzled but the rest of the files are fine. looks like a fairly simple swizzle.

Ah that's how you work with multiple files and filexor

I'll start working on fixing the sprites.

Ok so each tile sheet is actually four 8bit indexed sheets in one, just access a different color channel to get to them.
The palette file contains one complete 256 color palette per row, just take the colors as they are.

The SPR file contains axis data and data on how to put together the sprite tiles.

Header (8 Bytes)
4 bytes - Number of sheets
4 bytes - Number of sprites

Sprite Header (20 Bytes)
2 bytes - Group# (will explain later)
2 bytes - Spr# (will explain later)
2 bytes - Width in tiles
2 bytes - Height in tiles
2 bytes - X Axis
2 bytes - Y Axis
2 bytes - Sprite width (tile width * 32)
2 bytes - Sprite height (tile height * 32)
2 bytes - Number of tiles in this sprite
2 bytes - Palette# (Which row to use in the palette file)

Sprite Data (8 bytes per tile)
2 bytes - Sheet#
1 byte - Tile#
1 byte - Channel# (0-3, the order being ARGB)
2 bytes - Tile position X
2 bytes - Tile position Y

Nice job that makes sense.
i saw the textures were aligned by multiples of 32 that makes sense.
