2013-01-05Mess with Mode 5 some more. Secret of Mana's menu sprite is fixed; however, ↵Nebuleon Fumika
as of commit 3cd20e203f3b0af8c32921f86547a126d74b34eb (still not fixed in this commit!), Donkey Kong Country's Rareware icon is split by black columns.
2013-01-04Move all CPU cycle calculations into cpuops.cpp.Nebuleon Fumika
2013-01-04Move 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.
2013-01-02Sleep when the lid is closed AND emulation is running. I don't know to what ↵Nebuleon Fumika
extent this will save on battery usage, though I do set the DSTWO's CPU to the lowest frequency while it sleeps.
2013-01-02Release 1.13.Nebuleon Fumika
2013-01-02Make Display Mode 4 an antialiased whole-screen mode.Nebuleon Fumika
* source/nds/displaymodes.cpp: Rewritten, assigned copyright to myself (GPLv2). * CATSFC/system/language.msg: Changed the English and French text for display modes.
2013-01-01Remove 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.
2013-01-01Render double-width-res tiles from Background Mode 5 as half-width tiles. ↵Nebuleon Fumika
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...
2012-12-31Release 1.12.Nebuleon Fumika
2012-12-31ppu.cpp: Store multiplicands and quotients using aligned 16-bit writes ↵Nebuleon Fumika
(little-endian). Fold more identical case statements in the huge switch.
2012-12-31Fix PPU resets. This fixes Legend of Zelda: A Link to the Past.Nebuleon Fumika
2012-12-31MIPS 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.
2012-12-30Image modifications.Nebuleon Fumika
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.
2012-12-30'make release' is now a thing. It makes the .zip file for a release.Nebuleon Fumika
2012-12-30source.txt: Merged to ShadauxCat's repository. Update the source link.Nebuleon Fumika
2012-12-30Update list of contributors in the copyright file.Nebuleon Fumika
2012-12-30Bump to version 1.11 for another release.Nebuleon Fumika
2012-12-30Return to 22050 Hz audio. 48000 Hz was just too much to handle, apparently.Nebuleon Fumika
2012-12-30Clean up some backslashes at the end of lines.Nebuleon Fumika
2012-12-30Memory access optimisations in sprite rendering.Nebuleon Fumika
2012-12-30Rendering optimisations.Nebuleon Fumika
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.
2012-12-28Transform macros into loops to render tiles.Nebuleon Fumika
At -O3 these get unrolled; at -Os they become shorter code, fitting into the cache with other code.
2012-12-28Revert "Test commit, look for write privilege."Nebuleon Fumika
This reverts commit a3fa0c23adc3ff77e72ce27257d837cc82f7b4b0.
2012-12-28Test commit, look for write privilege.Nebuleon Fumika
2012-12-27Merge pull request #26 from Nebuleon/masterJaedyn Draper
Merge to CATSFC 1.10+
2012-12-28Keep the audio processing unit (APU) enabled even when the user disabled the ↵Nebuleon Fumika
audio for a game. This allows some games that synchronise on the APU's actions to continue working.
2012-12-27Revert "Switch to the more complete Snes9x 1.53 documentation." It doesn't ↵Nebuleon Fumika
match the version used in NDSSFC, and I failed to port to 1.53 anyway. This reverts commit 2b23b5cbaf15bccc2aae0ff3ee91cedd26f101bd.
2012-12-27Make cleanly without -DCPU_SHUTDOWN.Nebuleon Fumika
2012-12-27Accidentally committed the previous revision with sound functions emptied.Nebuleon Fumika
2012-12-27Speed up rendering by an unknown amount.Nebuleon Fumika
gfx.cpp, others: Avoid always checking for Settings.SixteenBit if FOREVER_16_BIT is defined. port.h: Define FOREVER_16_BIT below PIXEL_FORMAT.
2012-12-26Add the update methods for the upper and lower screen into defines.Nebuleon Fumika
2012-12-26Merge Registers structures into their respective CPUs to avoid additional ↵Nebuleon Fumika
memory addresses being loaded every opcode.
2012-12-26Smoother sound. Raise the sound sampling frequency to 48000 Hz.Nebuleon Fumika
2012-12-26Universally use update method 2 for the lower screen and 0 for the upper ↵Nebuleon Fumika
screen. Method 1 causes problems after about 15 minutes; despite the double-buffering, screen updates start to tear in the middle consistently.
2012-12-26Wait for keys to be released after the yes/no dialog for deleting saved ↵Nebuleon Fumika
states, instead of delaying.
2012-12-24Readme to version 1.10.Nebuleon Fumika
2012-12-24Bump version number to 1.10 for the APU half-carry bug and optimisations.Nebuleon Fumika
2012-12-24End 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.
2012-12-24Bump to v. 1.09. Update the readme for cheats. Update the github link in ↵Nebuleon Fumika
source.txt.
2012-12-24Merge branch 'optimisation'Nebuleon Fumika
2012-12-24Merge branch 'cheats'Nebuleon Fumika
2012-12-24Make the GUI accept and save Snes9x's cheat file format. Improve support for ↵Nebuleon Fumika
saving the values present in ROM/RAM before a cheat is applied. Beautify the cheat selection menu, making it more tabular.
2012-12-23Correctly handle multi-part codes, for all cheat types (GG, PAR, GF).Nebuleon Fumika
They are currently loaded as multiple codes, however.
2012-12-23Screen tearing-related fix.Nebuleon Fumika
2012-12-23Various 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.
2012-12-22Preliminary 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.)
2012-12-22Correct the font. It formerly displayed columns every 8 pixels.Nebuleon Fumika
2012-12-21Previous update made it impossible to press the Right and Down keys.Nebuleon Fumika
2012-12-21ppu.cpp: Sync fewer bits of the joypad.Nebuleon Fumika
2012-12-21Eliminate 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.
