2013-02-08Require one audio buffer to be free again. Otherwise, if the 4 buffers get ↵Nebuleon Fumika
full, it's already game over, and getAudiobuff becomes NULL for about 400 milliseconds, stopping all emulation.
2013-02-07Synchronise fractions of a hertz correctly in the audio output timing code ↵Nebuleon Fumika
to avoid buffer overruns. Buffer overruns pause the game for about half a second.
2013-02-07Remove remnants of a failed auto-CPU implementation. Changing CPU speeds ↵Nebuleon Fumika
on-the-fly is just not stable on the DSTwo.
2013-02-07Stop inlining the regular tile drawing code. That was a micro-optimisation, ↵Nebuleon Fumika
and this revert brings the code a bit closer to mainline Snes9x.
2013-02-07Allow the user to be pressing a button when the emulator starts. This allows ↵Nebuleon Fumika
the Loading screen to disappear, and allows invoking New Game straight away.
2013-02-07README.md: Add more recent information about frame skipping and fluidity.Nebuleon Fumika
2013-02-07EN: Added a German translation. DE: Deutsche Übersetzung hinzugefügt.SignZ
2013-02-07De-interleave the ROM using DMA. This helps the more esoteric jumbo memory ↵Nebuleon Fumika
maps load faster.
2013-02-06Remove 320 KiB of memory allocations in APU emulation that were completely ↵Nebuleon Fumika
unused but constantly re-zeroed. Frees up 320 KiB for other uses, and saves ~4 milliseconds at emulator startup, when resetting the APU and when loading a new game.
2013-02-06gui.c: Require all keys to be released after the B, A or X button or the ↵Nebuleon Fumika
Touch Screen is pressed. This avoids bringing up, or exiting from, multiple menus if you happen to press something for longer than 1/5 second. The modification does not apply to the directional pad in all menus, or the L and R buttons in file selectors.
2013-02-06Use key pictograms from Pictochat to display keys for yes/no dialog(ue)s.Nebuleon Fumika
2013-02-06Yeah... Despite the audio optimisations, sound still crackles with display ↵Nebuleon Fumika
double-buffering. Disable that, again.
2013-02-06When changing languages, quit doing the "Changing language, please wait..." ↵Nebuleon Fumika
as it only takes a few milliseconds.
2013-02-06Raise the sound frequency from 22050 Hz to 32000 Hz, which is like the SNES. ↵Nebuleon Fumika
Use sound interpolation to make it sound even more like the SNES.
2013-02-06Fix 2 compiler warnings in gui.c.Nebuleon Fumika
2013-02-06Quit saving the files so often for nothing; that uses up erase cycles on ↵Nebuleon Fumika
storage cards! Instead, save them once when the menu that contains the settings that the user changed is exited, IF the settings' values changed, OR once when updating the list of most-recently played games. Automatically save the SRAM in most cases, including game changes. This commit also makes it unnecessary to save the game config of the previous game when loading another, makes it load certain settings correctly, and MAY make it avoid creating a file for a game's settings if the user never changes them from the defaults.
2013-02-06Reinstate frame skipping options 0 and 1, but keep the new meaning (>= 2 ↵Nebuleon Fumika
equivalent skip level) for automatic frame skipping. Remove the automatic CPU frequency option, which was making audio emit 0.25 second of silence every so often.
2013-02-06Allow all audio buffers to get full again before declaring underflow.Nebuleon Fumika
2013-02-06Fix the loading screen for a ROM appearing for a split second after the ↵Nebuleon Fumika
splash screen. Fix uninitialised memory access in Check_LoadArg.
2013-02-06Make all gamepak loads call LoadGameAndItsData, that way its "Loading" ↵Nebuleon Fumika
screen, current gamepak variables, game config stuff and so on are all consistent.
2013-02-06Fix settings not getting loaded with a ROM provided by plugin arguments.BassAceGold
2013-02-06Load the game from plug-in launch arguments. Make the CATSFC system ↵BassAceGold
directory become the one transferred via arguments in that case.
2013-02-06Document the auto CPU behavior a bit.Nebuleon Fumika
2013-02-06Implement automatic CPU frequency switching, which improves battery life if ↵Nebuleon Fumika
playing games that don't use all of the MIPS CPU. If all of it is indeed needed, then the game will constantly play at 396 MHz.
2013-02-05Force both manual and automatic frameskipping to be at or above 2. Resets ↵Nebuleon Fumika
the default value for all games which previously had this value configured.
2013-02-05Disable the free space line in the options for the time being. Currently it ↵Nebuleon Fumika
invokes a recursive directory scan to calculate how much space is used first.
2013-02-05Change the upper screen updates to be double-buffered. Require that one ↵Nebuleon Fumika
audio buffer be free (1 out of 4).
2013-02-05Add include files from BassAceGold's library, release 2 fix 2.2.Nebuleon Fumika
2013-02-04Fully integrate BassAceGold's libraries, finally. The README still states ↵Nebuleon Fumika
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.

2013-02-03Synchronise the controller status more spread out inside a rendered frame:Nebuleon Fumika
* 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.

2013-02-03Force waiting for a screen to be transferred (update mode 1) because ↵Nebuleon Fumika
otherwise the next screen can go into DMA. Use channel 1 instead of channel 5, which must be busy for some reason.
2013-02-03Fix a name clash between Snes9x's dma.h and the DS2 dma.h by renaming the ↵Nebuleon Fumika
DS2 dma.h to ds2_dma.h. Add preliminary support for drawing emulated screens with DS2 DMA.
2013-02-03Whoops. I forgot to replace an instance of ds2_setCPULevel from the ↵Nebuleon Fumika
experimental branch cherry-pick.
2013-02-03Add SDK modifications by BassAceGold as of 2011-04-14, as well as modified ↵Nebuleon Fumika
DMA functions as of 2013-01-29.

switch to the user's chosen frequency for the game. Conflicts: source/nds/ds2_main.c source/nds/entry.cpp source/nds/gui.c
2013-02-02Fix an oddity in the sound when returning from a global mute. Fixes music ↵Nebuleon Fumika
loading in Super Mario World.
2013-02-02Release 1.26.Nebuleon Fumika
2013-02-02Add the experimental branch's files to .gitignore.Nebuleon Fumika
2013-02-02Correct overzealous detection of buffer overruns. It was making the sound ↵Nebuleon Fumika
crackle constantly, like a record player. Most audible with earphones.
2013-02-01Release 1.25.Nebuleon Fumika
2013-02-01Add an option that controls which element should be more fluid, per game: ↵Nebuleon Fumika
video or audio. 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.
2013-02-01Revert the reversed stereo mixing loop. This makes it more consistent with ↵Nebuleon Fumika
mainline Snes9x, in case of merges from 1.53. It also didn't help much, given that the problem was trying to push 92 milliseconds of audio inside 20 milliseconds of time. This reverts commit 2b715684087675747df7cb8995695936f20c782b.
2013-02-01While killing time between frames, process audio instead of doing nothing. ↵Nebuleon Fumika
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.
