that 1.2 is required to overwrite 0.13's stuff; really, 0.13 is needed only for `gcc`. So the sequence goes 0.13's `gcc` -> 1.2 -> BassAceGold's libraries -> make `libds2a.a`.
DMA function names changed to match BassAceGold's.

* before rendering a background;
* before rendering sprites;
* while rendering more than 128 samples of audio at once ("Prefer fluid video");
* after every 16 scanlines of CPU execution instead of every 1;
* while waiting for an audio buffer to become available;
* while killing time between frames with fast-forward disabled.
Controller presses and releases are now combined in a DS button bitfield using a shorter 32-bit algorithm. See entry.cpp:NDSSFCAccumulateJoypad and #define ACCUMULATE_JOYPAD in the source.
This is still not suitable for playing platformers frame-perfectly, but it's much better than half a second of latency to press or release a button, and one still needs to press buttons a bit more than just light taps. I'd say 50 milliseconds is the latency now. Platformers requiring more precision can be played with frameskip 0.
DMA does not require double-buffered displaying, so synchronise the controller more often by disabling double-buffered displaying again.

Use channel 1 instead of channel 5, which must be busy for some reason.

This makes most games playable, but the player can choose to get fluid audio instead of fluid video in sound-test modes or games with epic soundtracks.

Also correctly fill the buffer with silence when returning from pause. This reduces or eliminates crackling.
The emulator kills time in two circumstances:
* In automatic frameskip mode, without fast forwarding, the emulator kills time if it rendered a frame early.
* In manual frameskip mode, without fast forwarding, the emulator kills time to wait for the next rendered frame.
|
|
* Fake out the buffer timing by sending a buffer full of silence when returning from pause. Reduces crackling introduced by the next point.
* Send buffers only once every 23.22 milliseconds, not up to four buffers at once (92.88 milliseconds) and randomly thereafter. Reduces note-length jumpiness.
* Audio may have trouble catching up if external jitter reaches 11.61 milliseconds. That happens if Mode 7 images or filtered modes take a long time to render, or if chips take a long time to execute.

These hotkeys can be overridden per game so that the global version of the hotkey can be ignored.
* Language file fixups related to \n (newlines).
* Pictochat fixups: shorten START and SELECT to ST and SEL. Should still be recognisable.

I know ds2_setBacklight(unsigned int) needs a delay before it, otherwise if done too close to another call, it crashes.

Reverses the auto frameskip synchronisation from commit dac11c74ac112728016e51625ac9f2a727152ddd, because that doesn't play well with interrupts.

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.
