Wrap the offset into the audio buffer less often.

99b19abca3 Remove 2 extraneous delays. The 100-millisecond delays before ds2_setBacklight() MUST STAY, however, otherwise the emulator can crash with the bottom backlight off if a touch is recognised twice in a row. That happens with some broken styluses, so it's not unexpected. 2013-01-12 20:35:47 -05:00

7896e83aa9 Stop constantly testing for 16-bit and stereo in sound handlers. Define FOREVER_16_BIT_SOUND and FOREVER_STEREO and use them throughout the code. 
This is essentially commit 6b36e79013, but for sound instead of graphics.

0028091d0f Fix the interrupts glitching sound. Put the sound back at 22050 Hz. 2013-01-11 03:31:03 -05:00

3a1708474f Reinstate some delays needed by the code to avoid crashing, and actually explain in code comments why they're needed. 
I know ds2_setBacklight(unsigned int) needs a delay before it, otherwise if done too close to another call, it crashes.

This partially reverts commit 8951fdff1a.

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

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.

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?).
