I doubt you can insert SPC files. It might be possible to import music from another game using the same music system (never worked with HM), but probably not. There is no specific format for music; it's up to the game programmers to make one up for their sound program, so usually 2 games' sound formats will be different, anything from the commands being in a different order to using an entirely different system (some games even stream low-quality wave files from ROM). Due to the limited memory available for sound programs, the lack of documentation for the sound chip, and the difficulty involved in communicating with it, switching programs mid-game or making a 'fully-compatible' program is difficult if not impossible (especially since one game's program most likely won't respond to another game's commands).
Now of course, programmers often do re-use the same music programs; for example, most of Nintendo's SNES games use the N-SPC program (I believe Zelda is one of them). However, there's still the matter of getting it into the ROM. SPC files are like a 'save state' from the sound chip; they don't contain the actual music data that you would put into the ROM. Also, instrument sets vary between games, so music from one may not sound so good in another.
So in short: No, in most cases you can't import music from another game, and when you can, it takes a fair amount of skill with hex editors and music in general. |
