  • 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! Nebuleon Fumika 2013-01-08 03:23:55 -05:00
  • e4d3aeac2a Release 1.15. 1.15 Nebuleon Fumika 2013-01-07 21:15:43 -05:00
  • 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. Nebuleon Fumika 2013-01-07 20:46:10 -05:00

  • 69eb5ddcba 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. Nebuleon Fumika 2013-01-07 04:38:35 -05:00
  • 6681d4ade7 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. Nebuleon Fumika 2013-01-07 03:26:53 -05:00
  • c61b48ad1a Add a section about frame skipping in the readme. Nebuleon Fumika 2013-01-07 02:38:03 -05:00

  • 1c48900fda Sync ALL bits of the joypad again. This may make controls a bit slower to parse, but is required by Super Mario All-Stars at least. Nebuleon Fumika 2013-01-05 04:01:01 -05:00
  • 6df0031bdb Mess with Mode 5 some more. Secret of Mana's menu sprite is fixed; however, as of commit 3cd20e203f (still not fixed in this commit!), Donkey Kong Country's Rareware icon is split by black columns. Nebuleon Fumika 2013-01-05 02:19:00 -05:00
  • 7c1327bd24 Move all CPU cycle calculations into cpuops.cpp. Nebuleon Fumika 2013-01-04 23:12:10 -05:00
  • bfef6f17bd Move some CPU cycle calculation from address resolution to the opcodes. This is to eventually move it from the resolved-address ops as well, reducing the number of memory stores. Nebuleon Fumika 2013-01-04 15:54:12 -05:00
  • 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. Nebuleon Fumika 2013-01-02 03:20:47 -05:00
  • 378f5a0e3f Release 1.13. 1.13 Nebuleon Fumika 2013-01-02 01:32:15 -05:00

  • 4846dfa867 Fix PPU resets. This fixes Legend of Zelda: A Link to the Past. Nebuleon Fumika 2012-12-31 19:09:18 -05:00
  • c5d385d664 MIPS requires 2-byte reads to be aligned to even addresses. #define FAST_ALIGNED_LSB_WORD_ACCESS and use it to read absolute 24-bit addresses as either 1 byte & 1 halfword, or 1 halfword & 1 byte. Nebuleon Fumika 2012-12-31 13:46:47 -05:00
  • 22fa90a3b3 Image modifications. Nebuleon Fumika 2012-12-30 17:00:24 -05:00

  • 1bdf314192 Return to 22050 Hz audio. 48000 Hz was just too much to handle, apparently. Nebuleon Fumika 2012-12-30 15:56:36 -05:00
  • 8956d5cff2 Clean up some backslashes at the end of lines. Nebuleon Fumika 2012-12-30 15:30:14 -05:00

  • 21c8ca9a1e Merge c01a2a4216 into 74211924af Nebuleon 2012-12-27 22:57:25 -08:00
  • c01a2a4216 Keep the audio processing unit (APU) enabled even when the user disabled the audio for a game. This allows some games that synchronise on the APU's actions to continue working. Nebuleon Fumika 2012-12-28 01:45:40 -05:00
  • 09b5fdb861 Revert "Switch to the more complete Snes9x 1.53 documentation." It doesn't match the version used in NDSSFC, and I failed to port to 1.53 anyway. Nebuleon Fumika 2012-12-27 18:51:20 -05:00
  • c8935c352c Make cleanly without -DCPU_SHUTDOWN. Nebuleon Fumika 2012-12-27 18:46:37 -05:00

  • e5869adc44 Merge Registers structures into their respective CPUs to avoid additional memory addresses being loaded every opcode. Nebuleon Fumika 2012-12-26 14:42:02 -05:00
  • 139c793b58 Smoother sound. Raise the sound sampling frequency to 48000 Hz. Nebuleon Fumika 2012-12-25 22:44:39 -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. Nebuleon Fumika 2012-12-25 16:00:34 -05:00
  • 7f0e1fee81 Wait for keys to be released after the yes/no dialog for deleting saved states, instead of delaying. Nebuleon Fumika 2012-12-25 03:18:36 -05:00

  • e7ce8dd66c Bump to v. 1.09. Update the readme for cheats. Update the github link in source.txt. 1.09 Nebuleon Fumika 2012-12-24 02:15:42 -05:00

  • d1fe64aef0 Various optimisations in the CPU emulation. Nebuleon Fumika 2012-12-23 16:13:54 -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.) Nebuleon Fumika 2012-12-22 22:16:55 -05:00
  • 7701191d82 Correct the font. It formerly displayed columns every 8 pixels. Nebuleon Fumika 2012-12-22 15:40:43 -05:00
  • e7f7d0282a Previous update made it impossible to press the Right and Down keys. Nebuleon Fumika 2012-12-21 14:56:23 -05:00
  • 371058df32 ppu.cpp: Sync fewer bits of the joypad. Nebuleon Fumika 2012-12-21 11:57:45 -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. Nebuleon Fumika 2012-12-21 03:50:10 -05:00
  • 3972512b2a Looks like only having 'lang' crashes the options dialog. Restore the array of pointers. Nebuleon Fumika 2012-12-21 01:44:57 -05:00

  • cba2a156f8 Somehow the C (language specifier) from a code block made it into the readme. Nebuleon Fumika 2012-12-20 19:08:18 -05:00
  • dfab02b913 Use Markdown-style sections. I thought == == worked... Nebuleon Fumika 2012-12-20 19:06:04 -05:00
  • 90fbc11b7a Fix the Engrish in the readme. Make it a Markdown file for Github. Nebuleon Fumika 2012-12-20 18:57:32 -05:00
  • 8085880130 Remove the SNES Open Bus behaviour by default. Also simplify translation again. Nebuleon Fumika 2012-12-20 18:10:38 -05:00
