@goggles99, I'm not sure about that. You can post this in the FMOD forum (If you are talking about MiniFMOD library: mfmplay). The programmers of this libraries will answer you (I think ). Look at hxxp://www.fmod.com.
You can go here for uFMOD library, Korean site (and I think you can talk about, but in Korean language): hxxp://www.asmlove.co.kr/bbs/zboard.php?id=asm_forum&no=6.
About C++ and uFMOD: hxxp://www.wasm.ru/forum/index.php/index.php?action=vthread&forum=5&topic=8986
The Canterwood site. You can get here asm sources of keygens that uses XM, and more more much . hxxp://canterwood.online.fr/
I think this will be useful four your projects!
