The Super Nintendo Entertainment System is one of the most powerful 16-bit consoles. The SNES used an extremely powerful graphics coprocessor able of generating real-time effects like scaling and transparency.

This release of SNES9X offers amazing emulation quality and performance, when compared to any other SNES emulator available today. This version supports TV Mode, mouse input, and GZ-compressed ROMs.

  • Fix for save state blocks > 999999 bytes. (Bisqwit)
  • C4 games now save C4 data in save states. (DeHackEd)
  • Unix: Framework for high-speed seeking. Specify a frame number in a movie, and the emulator will run at maximum speed to that frame. Untested. (DeHackEd)
  • X11: Support for window exposure. When a window is damaged due to overlay, being iconified, etc. it will be repainted correctly. (DeHackEd)
  • Unix: parameter: -autodemo loads a movie for playback on startup. Only the x11 code handles this right now. (DeHackEd)
  • Unix: parameter: -oldturbo, the turbo button renders all frames when fast-forwarding. (DeHackEd)
  • Unix: parameter: -upanddown, override U+D and L+R protection. (DeHackEd)
  • Unix: parameter: -mute, currently linux only, blocks out audio output from your speakers while still emulating sound. Not fully tested. (DeHackEd)

  • Unix: Non-blocking sound on Linux. It makes seeking nicer.(DeHackEd)
  • Unix: Configurable sound device. (pierredavidbelanger)
  • configure.in now requires a sufficiently new version of autoconf.(anomie)
  • Fixed slow versions of branch opcodes. (anomie)

    Touge Densetsu Saisoku Battle problem solved. (anomie, byuu)

  • Fixed superfluous auto-joypad-reading. (zones)
  • Fixed missing WRAM refresh during DMA transfer. (zones)
  • Fixed DMA so that HDMA and any HC triggered events can run during DMA transfer. (zones)
  • Roughly fixed the case that HDMA and DMA use the same channel at the same time. HDMA kills DMA. Thanks byuu. (zones)
  • Changed initial DMA registers values. (zones)
  • Slightly modified APU execute timings. (zones)
  • Fixed APU I/O registers to get/set the proper value. (zones)
  • Blocked invalid VRAM writings, though you can turn off this option due to Snes9x's inaccurate timings. (zones)
  • Omitted SPCTOOL, no one uses it. (zones)
  • Added Sufami Turbo support. (zones)
