memory addresses being loaded every opcode.
2012-12-20Remove the SNES Open Bus behaviour by default. Also simplify translation again.Nebuleon Fumika
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.
