using the PSG to actually play music is more valuable than having an extra channel on the ym2612 in my opinion, and the 2612 dac is way more useful. In a pinch I guess you could do some simple high-frequency sound effects with 1-bit pcm, but it won't be enough for percussion. http://www.youtube.com/...

I believe the z80 almost exclusively plays music in the Sonic games. It sits in a tight loop manipulating the ym2612 and sn76489, usually using the vblank interrupt for timing. The ym2612 does have timers, but it takes a lot of cycles to check them and can slow down playback and reduce the complexit...

It is not easy to play PCM at the same time as playing music. It is possible, but not with these simple drivers. My custom hardware VGM player still slows down a little while playing PCM samples and 5-channel music simultaneously, and it's going to take a coprocessor to fix that. The stuff Genesis d...

chances are the less charitable people would have found out either way. I wouldn't have heard about it or donated if I hadn't heard about it in this thread. So, it's all good. Let's just outbid them. Also without us all donating and rallying for these things I bet the auction value would be signific...

Okay, that bitbang mode for the FTDI looks pretty nifty. In linux, the drivers are in the repo for Ubuntu/Debian, so I don't see any problem on that front. They have both proprietary and open source drivers - I just installed the open source ones. There's plenty of info and examples on using bitban...
