AV data

Video

The video files are stored using the USM format developed by CRI Middleware. There is no compression being done. Tools like VGM toolbox can decompress these files.

Audio

There appears to be three “audio”(?) formats used in the game - MUL, SAM, MUS.

MUL

MULtiplexed Audio File.

Aside: MUL files between different versions of the game are practically identical. This is how the Japanese mod was made - all I had to do was the flip the headers to LE.
