Structure:
typedef struct header{
char ID[16];// = "RAYS MEDIA FILE\0";
int unkn1a[2];
int filescount;// number of files in this container
int unkn1b[3];
} header;
typedef struct filedescriptor{
char filename[32];//with trash (?) after first '\n'
int offset;//offset from beginning of file to IMG256
int size;// size of IMG256
} filedescriptor;
typedef struct IMG256{
char ID[16];//= "RAYS IMG256 FILE";
int unkn2[4];
int size_of_data;
char palette[3*256];
int offset_to_data;//offset from begin of this struct; always 0x328;
char pixeldata[size_of_data];
} IMG256;
So, format of pixeldata in IMG256 is unknown, width and height are unknown too. Pixel data looked like packed (RLE?).
If anyone can help... welcome!
