The hardware is running on a modified Littlescale Open Source Teensy code for the SN76489. (which is not the GenMDM nor the SMS device one) I have modified how the voices are handled to avoid the cutting of the notes when you press a new key without releasing the previous and some other tweaks here ...

Yes, but assuming if my driver is changing instruments frequently, it can't guarantee that release rate is enough to reset volume to lowest, when I change instrument. So I can get unexpected behavior when some instrument with low release rate was changed to some instrument that assume all TL at low...

What happens is that the Phase is reset during KEY ON but not the current attenuation level ! That means that although you KEY OFF with all 4 bits to 0 , the attenuation will start where it was. This simply because when you KEY OFF you force the envelope to the release stage directly. The release st...

They still "rotating" during key off at high levels. I just wondering, is it supposed to work in tha...

It could be not that hard if it is only simple music.. (simple notes, no custom techniques). First the AY frequency counter is 12-bit versus 10-bit on the PSG which allows for a lower frequency range. (ex: PSG lowest Tone FRQ possible = counter set to 1024 = 109.239044 Hz (NTSC clocked)) Secondly th...

RAM and registers are loaded with garbage on startup, you need to do some setup on those. TMSS units do some of that cleanup. So in that case, why my early non TMSS loads fine and the TMSS not? + the Hard reset option on the Everdrive should clean system registers b4 game starts. http://krikzz.com/...

garbled display...probably not your custom card. As previously stated it runs fine on my early model 1 (PAL, don't remember which VA but probably early one with external joy port and high-def graphics mention). On another PAL MD later revision (with TMSS and no High def mention) I have the garbled d...

I think I will get me a MegaEverdrive at some point, USB in/out features sounds interesting... Worth mentioning that Regen or GenKmod can already save dumped channels as .tfi format :) IIRC the Basic Everdrive features a SRAM save function and will save a .srm file onto the SD card, then it should b...
