the so-called 960/1000 color methods are not viable because these are just tricks that would be hard to calculate for real-world scenarios according to what's actually displayed on screen. The method nemesis describes is not possible because there is not enough time during hblank to write a new pale...

*cough* ^ not entirely sure why people keep ignoring this.. And with a SGDK implementation on the way (almost finished), this should be almost perfect. I've been experimenting with setting different YM timer values to make it faster. And it works pretty well, but PCM timing must be a bit more smoot...

I'm currently trying Shiru's TFM Music Maker as it indirectly supports MIDI files. As in, use OpenMPT to convert MIDI to MOD and then use TFM Music Maker to convert MOD to TFD. Assigning instruments and timing issues still prevent me from being successful. I don't even know where to begin with that...

PCM output still works when DAC is turned off but $2C is turned on (!!) ok, I think I get it, probably this is a "special" DAC mode: $2B enables DAC on channel 6 and $2C on all channels. you should try with all channels being muted except channel 6 and see if there is any differences with $2C bit o...

Nice find. Although I didn't get some of the explanation and conclusions. Especially these ones PCM gets set to FM TL 0 instead of the set value of FM TL 16 (this cannot be changed in any way as far as we know, the only bit that does it is this one) channel 6 when in PCM mode ? I don't get what you...

Undocumented YM2612 register $2C
Hi, I will now present my notes on the previously undocumented register $2C on the YM2612. A little backstory: Back in 2008 I was working on a Sonic 1 hack called "Sonic 1 Oergomized". I was porting music from Columns III to the Sonic 1 sound driver. Because I wasn't able to do it manually because I...

I've tried it and it looks like it's crashed. I've got "Start transfer.exe and send a program!", then the same note playing over and over. I'm running on a Genesis II. No idea what kind of chips it has inside. Thats normal. Because the rate is so high the PCM sample played is very short. If you get...

Everybody who can run this program:
http://www.mdscene.net/~pvt/RAMDEV_BUILT.BIN
And tell me if his machine crashes. It stuffs ~152000 bytes per second into the YM while playing a FM instument. tell me if your machine crashes!
