2012-12-30	Add support for pc indexed addressing mode to lea	Mike Pavone

2012-12-30	Support more address modes for jmp	Mike Pavone

2012-12-29	Fix swap	Mike Pavone

	incorrect results once translate_m68k_src was fixed

2012-12-27	Fix pc indexed addressing (probably) when used as a source	Mike Pavone

2012-12-27	Initial work on allowing dynamic branches and code in RAM plus a small fix ↵	Mike Pavone

2012-12-27	Fix some bugs in emulation of CLR	Mike Pavone

2012-12-26	vertical interrupts now work	Mike Pavone

2012-12-26	RTE doesn't crash the emulator anymore	Mike Pavone

2012-12-26	Initial stab at interrupt support. Make native code offsets bigger so I ↵	Mike Pavone
	don't have to worry about overflowing the offset. Implement neg and not (untested).
2012-12-22	Add support for indexed modes as a source, some work on jmp and jsr with ↵	Mike Pavone
	areg indirect mode
2012-12-21	Added untested support for LINK and UNLK	Mike Pavone

2012-12-21	Removed some old debug printfs	Mike Pavone

2012-12-21	Implement a couple of supervisor instructions	Mike Pavone

2012-12-21	Implement more instructions and address modes	Mike Pavone

2012-12-20	Fix BTST	Mike Pavone

2012-12-20	Gamepad support	Mike Pavone

2012-12-19	Cleanup 68K timing code. Temporarily omment out fFPS counter as it was ↵	Mike Pavone
	causing segfaults

	instructions other than move (untested) and fix decoding of MOVEM.
