goyuken cd2ff4ed63 Add unmanaged version of 6502X core. The core it self is nearly exactly a copy+paste job from the C# one; most things map over exactly. A strange and abusive p/invoke setup is required to realize a performance gain; see code for details. Seems to be worth a bit more than 20% overall speed for me. Core is savestate compatible with managed 6502X. slight modifications to existing API has been made to support the new cpu. also included is a test module that runs both cores together, savestating every cycle to check for sameness. Core should fit in Atari, although that hasn't been done yet. For the moment, tracelog and disassemble are broken, but they'll be back soon. 2012-10-30 23:01:54 +00:00

goyuken aa292b678e shorten some of the FDS mechanical timings based on nesdev feedback. bizhawk now seems to be about 6 seconds slower than fceux in initial loading of FDS titles.
