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
zeromus	b1d62ed574	6502-add some opcodes not handled by the instruction tests, but which are cursorily covered by the instr_timing test, which now passes	2012-04-18 08:04:06 +00:00

zeromus	d3321f552f	nes accuracy fixes ... - pass more apu_test 4-jitter and 6-irq_flag_timing (necessary for timing on other tests) - pass all cpu interrupt tests - pass all sprite hit tests	2012-03-25 09:25:27 +00:00
zeromus	471b3ffb98	nes-fix soft reset functionality which had got broken when i upgraded the cpu core	2012-03-18 03:46:06 +00:00
zeromus	2b21ca7127	add new, more detailed 6502X cpu core, use it in the nes core as experiment. win almost all the speed back, pass some more tests.	2012-03-15 21:28:37 +00:00
