2013-05-21	Finish SRAM support for games without a SEGA mapper	Mike Pavone

2013-05-21	Support for SRAM with SEGA mapper. Half-finished support for SRAM without ↵	Mike Pavone
	SEGA mapper.
2013-05-21	Refactor code gen for read/write functions	Mike Pavone

2013-05-21	Fix some minor copy pasta bugs that resulted in an unnecessary REX prefix ↵	Mike Pavone
	being generated for some instructions
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	Fix a region detection bug	Mike Pavone

2013-05-19	Don't sync the 68K clock to the VDP clock unless the 68K had to wait for the ↵	Mike Pavone
	VDP. This unfortunately breaks the direct color DMA demos, but should be more correct overall.
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

2013-05-16	Get frame time correct and frame rate sort of correct for EUR region	Mike Pavone

2013-05-15	Increase sample size for min_delay	Mike Pavone

2013-05-15	Re-enable frame limit, but add a command line flag to disable it	Mike Pavone

2013-05-14	Some Z80 interrupt fixes	Mike Pavone

2013-05-14	Only latch video mode at the very beginning of the frame to avoid problems ↵	Mike Pavone

2013-05-13	Fewer magic numbers in the VDP core for the win	Mike Pavone

2013-05-13	Added some basic VDP debugging features to debugger. Fixed DMA enable bug	Mike Pavone

2013-05-11	Properly mask sprite X and Y coordinates	Mike Pavone

2013-05-11	Remove z80_ram reference in SDL renderer to get stateview compiling again. ↵	Mike Pavone

2013-05-10	Implement hblank flag in status register	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.
2013-05-09	Add YM2612 stubs to transz80	Mike Pavone

2013-05-09	Fix return address for RST	Mike Pavone

2013-05-09	Show absolute addresses for JR, JRCC and DJNZ in Z80 disassembler	Mike Pavone

2013-05-09	Set the N flag to the correct value for DEC instructions	Mike Pavone

2013-05-09	Implement carry flag for shift instructions. Implement weird behavior for ↵	Mike Pavone

	instructions on x86
2013-05-08	Complete flag behavior for Z80 BIT instruction	Mike Pavone

2013-05-08	Properly handle negative displacements in Z80 core	Mike Pavone

2013-05-08	Contrary to the official documenation, OR and AND also set PV based on ↵	Mike Pavone
	parity instead of overflow
2013-05-08	Set PV flag based on parity, not overflow for XOR	Mike Pavone

2013-05-08	BIT was setting the zero flag to the opposite of what it should have. This ↵	Mike Pavone
	is now fixed.
