You have a nasty bug when loading a Z80 driver. In an incredibly rare chance, an interrupt can happen after z80 is stopped and before the Z80 stop check is cleared, soft locking the entire consol. Worse, once it happens, its consistent (at least on emulators). Please go here to disable your interrupts, politely of course

It appears that the original SMPS drivers were binary blobs. Doing the same for this driver should help with compatibility, and ease-of-use. Then again, only one disasm primarily uses asm68k, and the actual music would need building at assemble-time, too, making SMPS2ASM a dependency. Problem is, SMPS2ASM is bound to AS in its current state.

Perhaps the driver should be pre-assembled, and music should be assembled separately, with a copy of AS.

EDIT: nevermind

I need to strip out that dependency, anyway. Perhaps, I should add a 'CloneDriverInit' function, where the user provides a 'this is a PAL console' flag.

While not a lot of people may use it, i feel like it's a nice thing to have if someone is wanting to make there ROM hack work with the 32x/PWM channel for, well anything

PSG plays fine on Fusion, Regen, and Genesis Plus GX, but on hardware, it plays incorrect notes. I don't even know how this is caused.

I can also confirm this does this to the stock Sonic 1 music as well.

Add this

Very rarely, the Clone Driver v2 will freeze gameplay when attempting to change songs. It seems to happen in the SMPS_waitZ80 macro under "DACUpdateSample". The odd thing is, if I skip past the bne loop using regens' debugger, everything continues as normal. The music plays properly, DAC samples work as normal, and gameplay is completely unaffected.

I can provide a savestate, rom and maybe even some source code in private if necessary.
