News: FakeNES 0.5.8 is now available!

  • AUDIO: Fixed OpenAL once and for all.

News: FakeNES 0.5.x is now available!

It seems that a new FakeNES series was released while i was looking the other way. I added 0.5.1, 0.5.2, 0.5.3, and 0.5.4 to the FakeNES Official Releases page.

0.5.1 Official

  • AUDIO: Added audio Delta-Sigma filter.
  • AUDIO: Fixed pseudo stereo mode 2 by disabling noise cycling.
  • CODE: Changed default minimum CPU requirement on DJGPP and Mingw32 compiled builds to i586 (Pentium class), up from i486.
  • CODE: Makefile improvements, including automagic dependancy list generation.
  • CODE: Centralized all save data functions into 'save.c' and 'save.h'.
  • CODE: Split 'misc.h' into 'common.h' and 'types.h'.
  • CODE: Renamed 'crc32.c' and 'crc32.h' to 'crc.c' and 'crc.h', respectively, to allow for future additions to the CRC generation API.
  • CODE: Fixed version number to read 0.5.1 instead of 0.4.0 - it was broken in the January 13th WIP release, which was supposed to be 0.5.0. x_x
  • CORE: Removed x86 optimized core since it's benefits these days are questionable compared to the overhead it induces.
  • GUI: GUI overhaul, partial Unicode support, and more.
  • GUI: Added GUI toggle for Zapper emulation.
  • GUI: Changed default GUI theme to 'Panta'.
  • GUI: Changed display method for backgrounds less than 200 pixels high from stretched to centered.
  • GUI: Fixed background drawing in color depths higher than 8 bits-per-pixel.
  • INPUT: Added support for using the mouse as an input device.
  • MISC: Added a CPU usage option and subsequently a GUI menu with which to configure it.
  • VIDEO: Added support for 24-bit video modes (fullscreen and windowed).
  • VIDEO: Removed outdated 2xSOE blitters.
  • VIDEO: Overhauled all remaining blitters and combined multiple blitter variants together.
  • VIDEO: Added new DES and DESii blitters.
  • VIDEO: Added makeshift support for HQ2X, HQ3X, and HQ4X.
  • VIDEO: Changed default display mode under windowed environments from fullscreen to windowed; use a platform-specific driver or the 'Force Fullscreen' option to override.

0.5.2 Official
  • AUDIO: Temporarily disabled OpenAL by default - There is nothing wrong with the code but OpenAL implementations don't like buffers as small as FakeNES uses, and thus produce silence. That will be fixed when the audio system is overhauled.
  • CORE: Fixed a runtime assertion error by adding a check for the existence of CHR-ROM before attempting to build a CRC32 of it.
  • GUI: Fixed a bug that caused some GUI fonts to get screwed up after a moveable dialog was drawn.
  • NET: Temporarily disabled all references to NetPlay, since it was never implemented in the first place.

0.5.3 Official
  • CODE: Cleaned up timing code slightly.
  • GUI: Removed all remaining hacks leftover from the old GUI menu code.
  • MISC: Added quick save/quick load feature which uses it's own independant state slot. Note that quicksave files have an extension of .fsv.
  • MISC: Cleaned up ROM loading code.
  • MISC: Made most code that deals with ROM filenames Unicode safe.
  • MISC: Changed behavior upon task switch while running in windowed modes from 'SWITCH_PAUSE' to 'SWITCH_BACKGROUND'.
  • MISC: Added callbacks to stop and later resume audio playback when a task switch occurs while running in fullscreen mode.
  • MISC: Added region auto-detection for PAL (E) games (currently it defaults to NTSC for all others). Note that this feature must be enabled from the System->Region menu by setting Region to 'Automatic'.
  • NET: Initial work on new NetPlay engine.

0.5.4 Official
  • CODE: Switched to zlib/libpng license.
  • GUI: Cleaned up input configuration dialog a bit.
  • INPUT: Added ability to calibrate joystick devices.
  • VIDEO: Added Blargg's 'nes_ntsc' as a selectable blitter (palettes are not supported).
  • VIDEO: Removed support for image offset/zooming (as these features were never used anyway).
  • VIDEO: Renamed 'light_adjustment' to 'brightness' and changed it's absolute range from 63 to 100.

News: FakeNES January 13 WIP is now available!

Minor update, the last before a major overhaul.
Changelog and binaries are in the 2006 WIPs section

News: FakeNES October 31 WIP is now available!

Major update, VSync and audio are improved, added check for VRAM page buffering, and other misc fixes.

Changelog and binaries are in the 2005 WIPs section

News: FakeNES October 26 WIP is now available!

Major update, this is all of the work since the last WIP (12/26/04) that has been sitting in CVS (i mistakenly thought that it was broken code). It includes vastly improved audio (new buffering, new effects, improved playback), automatic VRAM page buffering (reduces need for VSync), a new (unfinished) GUI theme, and some GUI/code updates.

Full Changelog and binaries are in the 2005 WIPs section
