snes9x2005 - Snes9x 2005. Port of SNES9x 1.43 for libretro (was previously called CAT SFC). Forked from https://github.com/libretro/snes9x2005

Age	Commit message (Collapse)	Author
2013-01-13	Delete server.cpp and netplay.cpp.	Nebuleon Fumika

2013-01-13	Revert timer-interrupt audio, but not optimisations done since then. Get the ↵	Nebuleon Fumika
	controller status every scanline again.
2013-01-12	Peel loops, aka only unroll loops if their number of iterations is a ↵	Nebuleon Fumika
	compile-time constant.
2013-01-12	Loop unrolling sucks. It was adding loads of instructions per audio sample.	Nebuleon Fumika

2013-01-12	Remove redundant writes to support reverse stereo. Define ↵	Nebuleon Fumika
	FOREVER_FORWARD_STEREO.
2013-01-11	Stop constantly testing for 16-bit and stereo in sound handlers. Define ↵	Nebuleon Fumika
	FOREVER_16_BIT_SOUND and FOREVER_STEREO and use them throughout the code. This is essentially commit 6b36e79013d4c9273a96a9783a2bccdb516f174a, but for sound instead of graphics.
2013-01-08	Revert "Reinstate FAST_ALIGNED_LSB_WORD_ACCESS for 24-bit jumps." That's in ↵	Nebuleon Fumika
	port.h now. This reverts commit 3dd99ccae465c370613ded10794749d6253bfe8c.
2013-01-08	Reinstate FAST_ALIGNED_LSB_WORD_ACCESS for 24-bit jumps.	Nebuleon Fumika

2013-01-08	Reinstate SNES Open Bus. It was making Secret of Mana's introduction screen ↵	Nebuleon Fumika
	sound like a NES with a rusty audio controller.
2013-01-08	Remove Open Bus again. Stop synchronising controls so often, now that the ↵	Nebuleon Fumika
	audio variable latency problem is fixed.
2013-01-02	Release 1.13.	Nebuleon Fumika

2013-01-01	Remove unused files. This reduces the plugin's size by 214 KB.	Nebuleon Fumika
	unicode.c, unicode.h, charsets.c, charsets.h: UTF-8 is universally used in CATSFC. Drop unused support for GBK/SJIS encodings.
2012-12-31	Release 1.12.	Nebuleon Fumika

2012-12-30	'make release' is now a thing. It makes the .zip file for a release.	Nebuleon Fumika

2012-12-24	Merge branch 'optimisation'	Nebuleon Fumika

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.
2012-12-22	Preliminary Snes9x-based cheat code support. Not tested, because the file ↵	Nebuleon Fumika
	selection interface freezes when it gets to the folder containing Mightymo's cheat files, whereas it did not do this before with the converted Mightymo cheats. (335 files -> 679, though.)
2012-12-21	Eliminate the latency of button press recognition, which was bad enough to ↵	Nebuleon Fumika
	lose keys entirely sometimes, and could otherwise delay a button press or release by 200 ms. This was the entire reason I created the fork, and I finally did it! It syncs the controls every scanline of a frame, which costs about 60,000 MIPS instructions per frame to deal with. Luckily, the processor runs at 396 MHz, which means the cost of checking the controls is 1% of the CPU's power.
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.
2012-12-20	Add back the -mlong-calls optimisation. It shortens the plugin's code a bit.	Nebuleon Fumika

2012-12-19	Raise the CPU's clock speed to 396 MHz while loading ROMs.	Nebuleon Fumika
	Also raise the CPU's clock speed to 396 MHz by default, instead of 360 MHz, when emulating a ROM.
2012-12-19	Delete offsets.cpp, which is for a standalone tool that is unrelated to the ↵	Nebuleon Fumika
	emulator.
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.
2012-12-17	Remove more unneeded files.	Nebuleon Fumika

2012-12-17	Makefile overhaul.	Nebuleon Fumika

2012-12-17	Optimise for size. Allow the build process to use multiple CPU cores with ↵	Nebuleon Fumika
	make -jN.
