Nebuleon Fumika	f385752705	memcpy vs memmove: memmove correctly handles overlapping source and destination memory buffers, but is slower than memcpy in many implementations. When memory buffers don't overlap, memcpy may be more efficient. ... The DS2 SDK is such an implementation, so change many memmoves into memcpys.	2013-02-01 00:33:30 -05:00
Nebuleon Fumika	1896286ad5	Permanently remove NO_OPEN_BUS hacks. It was a premature optimisation.	2013-01-08 16:26:43 -05:00
Nebuleon Fumika	e5869adc44	Merge Registers structures into their respective CPUs to avoid additional memory addresses being loaded every opcode.	2012-12-26 14:42:02 -05:00
Nebuleon Fumika	8085880130	Remove the SNES Open Bus behaviour by default. Also simplify translation again. ... SNES Open Bus is a quirk of the memory subsystem that allow reads of invalid addresses to return the last byte read from memory. However, it is seldom needed by a game, and it costs 1 to 3 MIPS instructions per SNES instruction to emulate. If you need SNES Open Bus, you can remove -DNO_OPEN_BUS from the Makefile.	2012-12-20 18:14:24 -05:00
