A new way to do music on the Genesis

Over at my forum, a guy by the name of JoseTheBest took the SMPS music driver, as seen in Sonic 1, and disassembled it to a working source. Combined with this XM-to-SMPS converter by nineko, it's now possible to make XM mods (within certain restrictions to fit with the Genny, of course), and then convert them to a binary which can be used with the SMPS driver. I haven't used it myself, so I don't know how easy it is to use, but it seems like it could be helpful. Hell, on the C64 there are hundreds of different music drivers, so I don't think that having just a few different ones on the Genesis will be a problem (in terms of the coding scene).

Cool !!! But I'll stick to my MSE for MD/Genny (but first I need to finish it)

Seems like I misunderstood something. Is this driver is M68K based (I'm always thought that it is Z80 driver), or only M68K interface was disassembled, not driver itself?

I've seen games that use 68K for FM and PSG and Z80 for PCM (Atomic Runner)... IIRC Sonic has Z80 sound driver...

Sonic 1 uses a hybrid driver - 68k handles the FM and PSG, while the Z80 handles the DAC. Later Sonic games use a Z80-only driver. This uses the binary version of the Z80 driver, although someone by the name of Puto also disassembled it.
