FAMI Dumping project

So, thanks to GKill for this interesting cart. It was dumped a long time ago, but it took some time to determine how it exactly works, mostly in part mentioned further. For the first look it was the same "Master Fighter - The Wolrd Warrior" cart with the hacked title. But, actually it was quite different from the rest of MF hacks, it has sound samples for title screen, fighter shouts, fight start, etc.! Even if sound samples aren't so rare for the NES, and they may be long enough (just like Final Mission), but there is no way to put so much sound samples for the generic NES system, as here.
At the second look, it's actually have a extra sound cirquit on the cart's PCB. A small PLC chip makes a simple 4-bit DAC (actually, it may be ADPCM, but as soon as resulting sound is close enough to the original, I don't care ;)), and programm feeding it with samples by IRQ timer. So we have twice reducing of the samples size against 8-bit (7) PCM, and much more quality than DMC for DMC channel.
For this time, you can try it both on the latest FCEUmm and SVN build of FCEUX.
