I now have full stereo audio support on the MegaDrive2 style RGB video connector! This includes TIA audio, POKEY and YM2151. All audio is generated on the 7800GD, so no issues with volume levels between sound chips — all mixing will be user configurable.

Another end of day photo! RGB out is working remarkably well! Still some glitches, but extremely encouraging progress.

And all of this just from a cartridge… crazy, huh?

And to finish the day off, here’s the first bring up of the 7800GD RGB out! It’s very broken, but it’s a start!

Start of save state support and full 6 button pad support with 7800GD!
