Subject: 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.
