The emulator must first be credible. The rest does not matter. How can it be credible while running like a slideshow? With skipping sound? It would be next to useless. Want some help moving the YM2612 to the ME? I intended to do that myself, but never had time for it. It could be tricky to do witho...

Yeah, with its "sound". *Sigh*. If GP2X and PSP had YM2612 inside, the emu would have perfect sound. But now having just 200/333MHz I just can't do rendering at the native rates with interpolation, accurate SSG-EG and stuff like that (unless you want it to run @ 5fps). After doing CPUs and graphics...

Also, it will have 100% compatibility (commercial games). Isn't that claim a bit arrogant, uh? I see it for a while now in your readmes. Even if those recently mentioned games really worked, do you really think all commercial games would work from start to completion, in all game modes without a ti...

I've checked what commercial games do again, and they use register, immediate values or RAM as their source operand. Here are some examples: move.w $f640.w, (A5) ; a5=00c0000 move.w D0, (A4) ; a4=00c0000 move.w (A1)+, (A0) ; a0=00c00004, a1=ffffe4be There are some games (mostly Konami) which only us...

what did you do exactly to fix the MAME core ? I changed the start of refresh_fc_eg_slot() to this: INLINE void refresh_fc_eg_slot(FM_SLOT *SLOT, int fc, int kc) { int ksr, fdt; /* (frequency) phase increment counter */ fdt = fc+SLOT->DT[kc]; /* detect overflow */ if (fdt < 0) fdt += fn_table[0x7ff...

Tried to add handling for this into MAME core. It took a while to figure out that the behavior Nemesis described is not what actually causes the 'blip' sound, the blip comes from operator1, and the described operator2 behavior eliminates the 'blip' :) For some reason I'm getting the best results whe...

The best solution would be adding VDP FIFO support to Gens, but if you can't do that, and don't mind having special version of Gens made specially for that game, just add this hack: Do_Genesis_Frame() function, very first first 'for' loop, after these lines Fix_Controllers(); Cycles_M68K += CPL_M68K...
