03a0d3457b Attempt to fix the crashing with sound interrupts, part 2: Stop the timer before the menu, and restart it after it ends. 2013-01-09 03:21:44 -05:00

3585aa1c2a Increase the audio frequency to 48 kHz. Timer interrupt intervals and buffer sizes are also tested at 32 kHz and 44.1 kHz. 2013-01-09 02:32:24 -05:00

4f9bd94497 Configurable interrupt interval for the sound timer. Right now, only 22050 Hz audio at 2000-microsecond intervals works. 2013-01-08 15:08:53 -05:00

12c5afbe60 GLORIOUS interrupt-based sound playback. Now, the note-length-hopping problem isn't as apparent anymore, and automatic frame skipping doesn't go to 8 FPS all the time in Super Mario World. Thank the deities! 
Reverses the auto frameskip synchronisation from commit dac11c74ac, because that doesn't play well with interrupts.

7d57e5aa45 Require auto_equivalent_skip to be greater than 0 before decrementing it if the code is drawing a frame early in automatic frame skip mode. Otherwise, overflow occurs, and we skip 4 billion images. 2013-01-07 20:46:10 -05:00

Remove old automatic frameskip code.

dac11c74ac Smooth out the automatic frame skipping such that it doesn't go from 1 FPS to 8 FPS right away and constantly. The equivalent frame skip will be 2, 3, 5 or 8 most of the time, depending on the game, and will vary a bit depending on rendering demands. 
For example, the frame skipping in Super Mario World is 3 on the map and in graphically simple levels, and 5 in complex levels.

8447b6304c Fix an off-by-one in the manual frameskip code. It would raise the sound speed by 25% if frame skip 3 (Show 1 in 4) rendered a frame early. 
Optimise the controller code. I don't expect to allow remapping any time soon, because the DS has buttons for every single SNES controller button and nothing more.

c01c25febe Add support for user-selected and automatic frame skipping. Add support for PAL timings (20 ms per frame). 
User-selected frameskip causes slowdowns if the game runs slower than the resulting frame rate, but synchronises correctly if the game runs faster.

Automatic frame skipping is still the default. It now only skips up to 8 frames, but in some games still skips that entire 8 frames. What's needed is an algorithm that averages frame latencies over a few seconds and skips while the latency is LOWER than the average.

6c5bd75716 Language file overhaul, part 2. Remove unused messages in all languages. 
It's actually reloading icons that takes so much time.

81cf5b3cd1 Language message overhaul, part 1. 
Clean up the names of messages. Mark those that are unused as such in code comments. Raise the CPU level while loading a message file, because it really does take half a second to load a 16 KB file on the lowest frequency (what the eff?).

7c2a30c5b5 Sleep when the lid is closed AND emulation is running. I don't know to what extent this will save on battery usage, though I do set the DSTWO's CPU to the lowest frequency while it sleeps. 2013-01-02 03:20:47 -05:00

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

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.

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.

8085880130 Remove the SNES Open Bus behaviour by default. Also simplify translation again. 
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.
