GENESology (or MDology?, depending)

The SNES-style music remix community SNESology recently had a regime change and the new community manager asked if I was interested in leading a Genesis-style music offshoot, tentatively called "GENESology" (or MDology for non-Americans?). For now, I've accepted, and would very much like more experi...

Would be very interesting to know how many cycles are needed for each type of register changes. I guess there'd be no other option than polling the state of the BUSY flag while counting cycles, right ? If I have to start counting cycles, then if byuu's higan and Nemesis's Exodus are any indication ...

I second this motion - I compose a lot of music!
I third this motion - YM2612.js needs some love! :)

Re VGM programs - maybe get in contact with ValleyBell about it? I know he made an entire suite of command-line programs to manipulate VGMs, including an optimizer, and while I haven't touched it in a long time I myself previously started work on an updated version of VGMTool that would also be cros...

He does both, conveniently enough, and has even written a SMPS+MIDI-to-VGM converter as part of his work :D

While I personally am partial to JavaScript (my love of the Sphere engine demonstrates such), Lua seems to be the current favorite language of new apps with embedded scripting.

ValleyBell is the guy to ask about SMPS, either on SonicRetro/SegaRetro, SMS Power, or vgmrips. He's also written many tools for processing it.

codeincomplete has a 4-part series on using Lou Gorenfeld's pseudo-3D procedures to create an Outrun-style racer in JavaScript; I'm pretty sure it's rather easy to port to another language. :)

With MIDI almost no one does micro-tuning, so multiplying by 2^(1/12) to get the default frequencies for the 128 MIDI notes for these purposes is safe. I just don't understand what you said just right now. What I meant was almost no-one uses micro-tuning other than "equal temperament," so my functi...
