Nebuleon Fumika	1896286ad5	Permanently remove NO_OPEN_BUS hacks. It was a premature optimisation.	2013-01-08 16:26:43 -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
Nebuleon Fumika	e708c127fa	Un-inline a bunch of stuff. ... With the MIPS instruction cache, this means that two consecutive SNES CPU instructions using e.g. the same addressing style or the same opcode have a chance that the second one will use the first one's code and that it will be cached.	2012-12-18 22:53:49 -05:00
