Yeah, found that and revisited my post. You posted the above before the edit. And we're just not going to agree on some of these points. So let's leave it at that.
Based on what I've read and understand of the code and how to implement it, it seems like the MSU-1 code could work rather well with ZSNES. But that is from an admittedly limited understanding.
Never understood the silly drama surrounding byuu. He's done great things and is still doing them. People really need to quit being so damn childish & petty.
EDIT; BTW, please don't take my perspectives the wrong way, I think what you're doing with MSU and SNES9x is most excellent!
