While I have been trying some SNES programming, I've never actually made a game engine in it.

I'm probably better at art and music anyway.

I actually make SNES music in OpenMPT and SNESMod, the latter of which actually outputs both SPCs and SNES soundbanks. I have never used SNESGSS, and I don't use DAWs. I have tried MML, and I didn't like it. My music is usually some form of EDM, but I have made orchestra simulations, and I also tend to make cracktro/keygen-style music as well. I like to mix genres, especially when sample space limitations force me to use extremely tiny single-cycle waveform samples and white noise.

I normally draw at resolutions of 512x448 or lower, though I am open to drawing at 512x478 and 256x239 for my PAL pals out there in Europe and Australia and Africa. I have experience with using GIMP to convert an RGB .PNG to an indexed image, and I have used SuperFamiConv many times to convert the result into actual SNES graphics data.
