Hi, what is this game name?

8bpp palette image, pixel index data is zlib compressed.

This is an exe conversion program.

These files cannot be processed yet.
vod25 uses some unknown compression algorithm.
vod26-28 contains 4x8BPP images, but lacks palette data. Also like 32BPP, but incorrect after parsing.

header 16bytes:
short unk;
short texType;//0x803=8bpp+zlib pixel. 0x800=8bpp no palette or 32bpp. 0x6 = look like 4bpp +unknown compress
short width;//realwidth = width + 1. and use right align
short height;
int datasize;
int pad;

vod27.ogt 8bpp:
