Changes

MIM files in the PC version of FF8 are a bit different from the MIM files found in the PSX version of FF7, there are no headers, no size information anywhere, the format seems to be fixed. Some files do not follow the pattern described below, presumably because they aren't paletted. Trying to load them using this scheme will result in a completely garbled displaytwo different types. These files can be identified by looking at Type 1 (the total filesizemost common) has 24 palettes and 13 128x256 texture pages, paletted files are always 438272 bytes while non-paletted ones are 401408 bytestype 2 has 16 palettes and only 12 textures.

The first section contains the palettes, always either 24 or 16 palettes of 256 colors in native PSX format (R5G5B5 with one mask bit) for a total of 0x2000 or 0x3000 bytes. The For type 1, the first 8 palettes are always the same, a repeating pattern of some basic colors, these palettes are never used, only the remaining 16 palettes can be accessed from the MAP file(?)

The actual image data can be read as a single 1664x256 256 pixels high image , 1664 pixels wide (always 0x68000 bytes) where one for type 1, 1536 pixels wide (0x60000 bytes) for type 2. One byte is one pixel and pixel values of 0 are transparent. FF8 splits the image into 13 multiple textures, each one 128x256, this is not necessary on modern hardware.
