I am not able to help you with the compression - in my opinion it may be custom. But I can help you at least with the file format and automatization of your research :D Thank you for helping out with the formats. My main target, besides that legal file, is the shell files, as they contain the fonts...

Greetings.

This file in particular contains the first screen with some legal credits. I have tried to put ...

Hi, I just tested the BMS script with the Spanish voice packs and some of these files are not decoded properly.

I was checking out the contents of the MIDI folder from this game when I found that, in Dreamcast (And also in PC, although it's unused), the MIDI files contain both PCM samples and ADPCM samples. Here's a ADPCM sample (With various concadenated audios). It should be at 11025 Hz, 16-bit, 1 channel f...
