2013-06-25	Use the registers that were freed up by the memory map function changes	Mike Pavone

2013-05-21	m68k_trap is now replaced with a generated one so it can call the generated ↵	Mike Pavone
	memory acccess functions. The old static memory access functions have been removed from runtime.S
2013-05-21	Generate handle_cycle_limit_int at runtime so it can refer to the runtime ↵	Mike Pavone
	generated memory map functions
2013-05-19	Handle busack across frame boundary	Mike Pavone

2013-05-18	Mostly working runtime generation of memory map read/write functions	Mike Pavone

2013-05-11	Don't update interrupt mask on non-interrupt exceptions	Mike Pavone

2013-05-11	Fix check for code writes	Mike Pavone

2013-05-10	Initial stab at horizontal interrupts and improving accuracy of vertical ↵	Mike Pavone
	interrupts. Also added the VINT pending flag to status port.

2013-04-21	Implement CHK instruction (not fully tested).	Mike Pavone

2013-01-15	Implement support for self-modifying code	Mike Pavone

2013-01-06	Print a message when we try to run an invalid instruction, not when we try ↵	Mike Pavone

2013-01-03	Implement TRAP (untested)	Mike Pavone

2013-01-01	Do a sync when interrupt mask changes so we can recompute the next interrupt ↵	Mike Pavone
	cycle. Also fix a bug in which the SR part of ORI to SR was not being performed.
2013-01-01	Make writes to control and data port block when DMA is in progress	Mike Pavone

2012-12-31	Implement m68k_modified_ret_addr	Mike Pavone

2012-12-30	Implemented HV counter	Mike Pavone

2012-12-29	Fix crash when printing error message about modified return address	Mike Pavone

2012-12-27	Use unsigned comparisons for address decoding, exit when we hit an unhandled ↵	Mike Pavone
	addressing mode for jmp
2012-12-27	Initial work on allowing dynamic branches and code in RAM plus a small fix ↵	Mike Pavone
	to effective address decoding
2012-12-26	vertical interrupts now work	Mike Pavone

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

2012-12-26	Fix Z80 BUSREQ/RESET implementation.	Mike Pavone

2012-12-26	Fix long reads from IO ports or long reads that trigger sync cycles by ↵	Mike Pavone
	saving rdi. Possibly fix word wide IO reads.
2012-12-26	Implement Z80 reset and bus request registers.	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).
2012-12-21	Implement word wide access to IO area	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
2012-12-18	ecx was getting clobbered before the relevant temp value was used in some ↵	Mike Pavone
	cases during memory reads
2012-12-18	Code in runtime for checking for VDP reads was using the wrong register. ↵	Mike Pavone
	This is now fixed.
2012-12-18	Get Flavio's color bar demo kind of sort of working	Mike Pavone

2012-12-16	Add preliminary support for JMP	Mike Pavone

2012-12-04	M68K to x86 translation works for a limited subset of instructions and ↵	Mike Pavone
