Anybody know how to extract audio files from the .hdi file of a PC-98 game? I've looked around some and save for some not very helpful posts on random forums made in the early 2000s, I can't seem to find any way of accomplishing this. It's for a homebrew game from the 90s, so no warez btw.

Tried VLC? You'll probably need some sort of ancient magic library.

More info on the game would be helpful, knowing the engine/development platform helps alot with decoding

VLC doesn't appear to work.

The game is the homebrew game by the cult Aum Shinrikyo.

Here's a link to the .hdi file on Mega. You can use this emulator to run it (Harddisk → SASI #0 → Open and then point to the file. Then select Emulate → Reset).

I can play it, but I have no idea how to extract all the soundclips it contains.

Loop back cable and record?

Yeah, my backup idea was just to play the game and record directly from my sound card but I was hoping for a more optimal way of getting the files. Oh well.

Thanks so much everyone for weighing in. I don't even know if the music is MIDI, as it sounds like looped snippets of recordings (which might still be MIDI?)

e: found something saying 001A00 is the hex to look for to extract .m files but I did that on a bunch of files and when playing it was just a bunch of corrupt sounding garbage, so hm. Also found https://github.com/suzukiplan/PMD-extractor but looking at the source it goes for the same hex but nevertheless I'll try compiling it in the morning, just because I like compiling stuff and this game seems really fascinating

I really appreciate all the info, thank you.
