* source/nds/displaymodes.cpp: Rewritten, assigned copyright to myself (GPLv2).
* CATSFC/system/language.msg: Changed the English and French text for display modes.
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.
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.
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.
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.
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.
* 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.
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.
EN:
* bdf_font.c: Add support for having a main font, [0], of more than 128 characters. Refactor character width checks into a new function, BDF_width16_ucs.
* bdf_font.h, draw.h, gui.c: Use UTF-8 for all strings to allow more translations. Use BDF_width16_ucs where possible.
FR:
* bdf_font.c: Prendre en charge une police principale, [0], de plus de 128 caractères. Diriger les vérifications de la largeur d'un caractère vers une nouvelle routine, BDF_width16_ucs.
* bdf_font.h, draw.h, gui.c: Utiliser le codage UTF-8 pour toutes les chaînes pour permettre d'autres traductions. Utiliser BDF_width16_ucs là où c'est possible.
