2014-10-30	apply a facelift	aliaspider

2014-10-28	64-bit safer	aliaspider

2013-01-08	Permanently remove NO_OPEN_BUS hacks. It was a premature optimisation.	Nebuleon Fumika

2013-01-04	Move some CPU cycle calculation from address resolution to the opcodes. This ↵	Nebuleon Fumika
	is to eventually move it from the resolved-address ops as well, reducing the number of memory stores.
2012-12-31	MIPS requires 2-byte reads to be aligned to even addresses. #define ↵	Nebuleon Fumika
	FAST_ALIGNED_LSB_WORD_ACCESS and use it to read absolute 24-bit addresses as either 1 byte & 1 halfword, or 1 halfword & 1 byte.
2012-12-26	Merge Registers structures into their respective CPUs to avoid additional ↵	Nebuleon Fumika
	memory addresses being loaded every opcode.
2012-12-24	End the use of global variables for CPU emulation. This creates fewer memory ↵	Nebuleon Fumika
	store instructions in many SNES, SA1 and APU opcodes. Fix the APU half-carry bug, which may be audible. globals.cpp: Get rid of A1, A2, A3, A4, W1, W2, W3, W4, Int8, Int16, Int32, Work8, Work16, Work32, Ans8, Ans16, Ans32.
2012-12-23	Various optimisations in the CPU emulation.	Nebuleon Fumika
	Run the opcode as a tail call from the address calculation. This cuts on the needed return instructions. Pass the opcode address as a parameter; this keeps it in a register most of the time and avoids memory stores.
2012-12-20	Remove 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.
2012-12-18	Un-inline a bunch of stuff.	Nebuleon Fumika
	With the MIPS instruction cache, this means that two consecutive SNES CPU instructions using e.g. the same addressing style or the same opcode have a chance that the second one will use the first one's code and that it will be cached.
