c43b58481f Remove unused files. This reduces the plugin's size by 214 KB. 
unicode.c, unicode.h, charsets.c, charsets.h: UTF-8 is universally used in CATSFC. Drop unused support for GBK/SJIS encodings.

3cd20e203f Render double-width-res tiles from Background Mode 5 as half-width tiles. This makes the menu text in Secret of Mana readable. 
Sprites in Background Mode 5 are still messed up. At least they're at the right X coordinate, roughly...

c5d385d664 MIPS requires 2-byte reads to be aligned to even addresses. #define 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. 2012-12-31 13:46:47 -05:00

22fa90a3b3 Image modifications. 
CATSFC/system/gui/boot.bmp: Remove the Engrish, although it was funny ("Enjoy yourself! All pleasure in it"). Replace it with a controller and the text "Loading...".

catsfc.bmp: Remove the CAT and replace it with a controller. In the .ini, it's already written as CATSFC anyway.

copyright: Update with image attribution per CC-BY-NC-ND 3.0.

source/images: Create, with .psd files for the two modified .bmp files.

d1d0c81af8 Rendering optimisations. 
tile.cpp: Optimise the common case of drawing an unclipped but possibly flipped 8x8 tile. Instead of calling WRITE_4PIXELS16 16 times, each performing setup and teardown, move the loop into DrawTile16.

tile.h, tile.cpp, gfx.h, gfx.cpp: End the use of global variable GFX.ScreenColors to pass around the current frame's palette. This saves on memory stores/loads.

e5a0c9146a Transform macros into loops to render tiles. 
At -O3 these get unrolled; at -Os they become shorter code, fitting into the cache with other code.

09b5fdb861 Revert "Switch to the more complete Snes9x 1.53 documentation." It doesn't match the version used in NDSSFC, and I failed to port to 1.53 anyway.

9c1742f6cb Universally use update method 2 for the lower screen and 0 for the upper screen. Method 1 causes problems after about 15 minutes; despite the double-buffering, screen updates start to tear in the middle consistently. 2012-12-26 11:29:47 -05:00

f29c76dc58 End the use of global variables for CPU emulation. This creates fewer memory 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.

f843d68bb6 Make the GUI accept and save Snes9x's cheat file format. Improve support for saving the values present in ROM/RAM before a cheat is applied. 
Beautify the cheat selection menu, making it more tabular.

They are currently loaded as multiple codes, however.

d1fe64aef0 Various optimisations in the CPU emulation. 
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.

a194b85003 Preliminary Snes9x-based cheat code support. Not tested, because the file 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.) 2012-12-22 22:16:55 -05:00

a0d0c5e7a5 Eliminate the latency of button press recognition, which was bad enough to 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.

5585c035fb Fix an off-by-one in the previous commit's touch handling code. 2012-12-21 00:05:07 -05:00

712c249e8c Simplify the GUI code. 
* gui.c: Simplify row and column checks when handling touch events.
* draw.c, err_msg: Use ConsoleInit instead of a custom drawstring function when an initialisation error that is NOT related to DS2 I/O occurs. This allows \r\n to work.
* gui.c, initialisation: Remove the Engrish in the "initial <subsystem name> error" messages. Make them appear in English and French. Unfortunately, the console doesn't support Chinese characters, and I don't know Chinese.
