I used the "Simpsons STR" QuickBMS script to open the game's archives which are the same format as The Simpsons Game (both were developed by EA). Those contain, amongst other things, the models of each level, which I'm trying to rip. I'm not really familiar with 3D file formats though, let alone compressed ones. Each file starts with the hex magic number 2F C3 31 6B
. The byte order is probably Big endian. There are also what seems to be data chuncks at the beginning of the files. the first ones start with "DFLT" and are 144 bytes long. the other ones start with "MULP" and are 304 bytes long. I couldn't find more information. Has this format been used in any other game? I'll attach sample files.
