Thank you for the answer, byuu. Don't get me wrong, your emulator is great, and I apreciate very much your commitment with open source. I simply pointed about the Nesticle patches were not necessary for speeding up the emulation, and that 3GHz was overkill, in my opinion. I bet in the future it will be much faster, no mater if is optimized by yourself o by others (I understand that may be optimization is not your goal, my point is just that the 3GHz is not a requirement just because precission, but because of current implementation). Best regards, and please, excuse me for telling you "idiot" in a previous post, change it by "innacurate" (Nesticle thing) and "incomplete" (3GHz required not only because accuracy, but also because current implementation limitations).
