Creating music files (PMD .M files) for PC98

[GoKonRin]

I'm trying to find a way to Turn off the music of SoEW and PoDD while maintaining the sound effects (in game options disable all audio completely).
I have tried deleting the .M files but the game becomes laggy and glitchy.

Is there a way to create a silent .M file?


EDIT: Yay! I figured it out:

First I need to compose some music (if you can call a second of silence "music") using modern Music Macro Language: http://en.wikipedia.org/wiki/Music_Macro_Language
Then, I need to use a compiler MC.EXE which can be found here: http://www5.airnet.ne.jp/kajapon/tool.html
After that, I  booted up my PC98 emulator and compiled my MML file into an .M file.
Finally I just need to use it to replay the .M of the game and repack everything back

Who would have thought fiddling with old computer systems can be that much fun

It sounds like it's constantly polling the system for the music files and wasting processor resources.
Unfortunately I couldn't find any relevant information. Unless there is an emulator out there that can disable individual sound channels. That's all I can think of right now.

hmmm,  I wonder if there is a software that can generate a .m file that is silent, Most PC-98 software I can find on google seem to be in Japanese :S

PC-98 owner here. I don't know where you are finding the .M files within PoDD and SoeW, but erasing them probably isn't the best idea.

I haven't found a specific program for shutting off OPNA sound channels (yet), but there may be one on Vector (http://www.vector.co.jp/). You will have to use Google Translate's website translation tool, however, because very little translated/English PC-98 software exists (PC-9800 series computers never appeared outside of Japan). Vector is an excellent site to find PC-98 software on; I've found everything from PMD .m players to i486-specific memory managers. Just make sure your computer is in the Japanese locale while you work with PC-98 DOS files.

If you can't find anything on Vector, then "Hertzdevil", a PC-98 composer, might be able to make you a "silent" .m file. He also knows how to swap .m files around within the code of the PC-98 Touhou games, so I'd try and contact him about making you "sound-only versions" of SoEW and PoDD.

Thanks for your reply, I'll try out the stuff at Vector and see if I can working through google translated japanese XD

As for the .M files, I first take out the .DAT files using the diskexplorer, and then extracted the .DAT using TH toolkit to get the .M files. I just need to modify or substitute the appropriate .M files and then pack everything back in to create a audio modified version of my game
