Vagrant Story:ZND files

The ZND files define groups of rooms, i.e. Zones. They define references to enemies (ZUD files) and textures to be used by the individual rooms which are defined by the MPD files.

Notes

The TIM format mostly follows wiki.qhimm.com/view/PSX/TIM_file.

However, there are some differences. The last 4 TIMs are usually, with some exceptions, palettes with 16bit actual color values. All the TIMs before are 4-bit color maps, and have been successfully exported as grey textures, without color lookup. All of the TIMs are defined as BPP = 10 and there never are CLUTs (need to confirm this).

Todo

The color lookup for the 4-bit color maps has not been understood yet. Some of the palette TIMs have more than 16 colors and hence, the lookup cannot be a direct palette lookup.
