I feel that it's silly to justify not emulating a core feature of the hardware "because it would allow techniques that are not feasible for games".an overwhelming majority of the projects you'll come across are written for an expansion chip, zero of which were available outside of the japanese market, and were only utilized for a handful of games. Member for: 4238 days Location: Canada Status: Offline Regarding the MMC5 PCM channel, it's a "software only" channel just like the way DPCM can be used, and offer no more than 1 additional bit of sample resolution.
#GOATTRACKER VS SID WIZARD FULL#
Tadpole: Doesn't goattracker allow full speed songs? But I don't think it would be as useful as on the NES because there is no way to disable the ADSR-envelope in the SID, to my knowledge.
#GOATTRACKER VS SID WIZARD CODE#
I thought it would be safe to leave it in the code only with no option to enable it, but that was a mistake :Dīut as I said earlier: be careful, as there might be things I need to change before it's complete. The reason mult-chip is allowed is entirely because I've added support for it, but I didn't intend it to be available before it was complete.
The only way to get around it is to change the tracker rather than the FTM. To answer the original questions: no it's not possible to hack a FTM to contain more than one DPCM channel, the reason is that the sound interface in the tracker is modeled strictly after a real NES. Member for: 3865 days Location: Milky Way Status: Offline It's just not a practical technique for games, which (with very few exceptions) tend to just stop everything they're doing when PCM sounds are being played. Now, you could use the MMC5 to play PCM samples at the same time as using the 2A03 to play DPCM samples, and that might be slightly worthwhile, but again, not really appropriate for Famitracker for the same reason that 2A03 PCM is not really appropriate for it. It's generally better to accept one less bit of effective resolution and maintain a higher samplerate, mixing all your sounds into one PCM channel (see SuperNSF). Trying to use a second PCM channel while doing this actually makes the problem worse because you'll need twice as much CPU, you'd have to cut your samplerate in half. It's extremely CPU intensive for the NES to do, and it's difficult to write a sensible playback engine that can use the other sound hardware and keep up with the PCM at the same time. Also it's unsupported by almost all NSF players, but that's another issue.Īnyhow, this all comes back to the old issue with PCM. Really, the MMC5 PCM channel is very much like the 2A03 PCM channel, except it is 8-bits wide instead of 7-bits. Perhaps you are mistaken because the one game that uses the MMC5 PCM happens to make no other sounds while it uses PCM.
The use of MMC5 PCM absolutely DOES NOT mute other channels.
