Snes9x is an open-source Super Famicom (SNES) emulator written in C++. It is also available as a libretro core for RetroArch.

Downloads[edit]

Derivative versions[edit]

  • Snes9x Next is an optimized version of Snes9x 1.52 with speed hacks and is available as a libretro core for RetroArch. It has an option to overclock the SuperFX chip, making games like Star Fox run at a higher FPS.
  • Snes9xTYL(mecm)/cm Mod is a port of Snes9x 1.39 to PSP. Inaccuracies everywhere, especially with sound, but it's the best thing available for PSP for SNES emulation. Use the mecm build where possible, unless you use the PSP emulator on Vita, in which case use the cm build.
  • ZMZ (GitHub and download page) is a version of Snes9x that uses ZNES' GUI with a Snes9x libretro back end.

Review[edit]

It is a very good Super Nintendo emulator, far superior to ZSNES. It has very high compatibility and is easy to use. It is not as accurate as higan but is good for systems that can't run higan at full speed. The stable release is very old, so use the latest dev build instead. One of the developers, OV2, hosts his own builds. Link above.

Problems and solutions[edit]

Snes9x stopped recognizing diagonals and joystick/R2/L2 input. Snes9x has issues with XInput (such as with XInput Wrapper SCP). The solution is to edit the .conf file and add in (J0)POV Up Right, (J0)POV Dn Right, etc. for the diagonal inputs.

Snes9k is Snes9x with Kaillera client support. It is based on a very old (~2005) build of Snes9x.

If using the updated multiplayer client[edit]

Review
PROS
  • Support for up to 8 simultaneous people playing
  • No fiddling with router settings and port forwarding
  • Netplay traffic is handled by a central dedicated server that helps keep things synched
  • Private game chat support and public chat to speak people outside your game room
  • Being able to drop out of a game at any time without disrupting (much) your teammate(s).
  • Kicking/banning/muting people from your room
  • It's a matchmaking service where you can join other people's rooms, too
CONS
  • It's slightly (significantly still) prone to freezing/crashing/BSOD (in that order)
  • Random, inconsistent FPS drops due to the server trying to keep everyone synched, sometimes stuttering. It's annoying, but rarely does it make it unplayable
  • The emulator is based upon (Snes9x 1.42, a 10-year-old version) lacks A LOT of options, and incorrectly emulates several games (most Bishoujo Senshi, DBZ Super Butouden 2, etc.)
  • Everyone needs to have the exact same ROM version or Netplay won't work (if it somehow does, it'll desynch rather quickly)
  • Everyone needs to have the exact same save file, or no save file at all. Else, it desynchs
  • You need to constantly switch focus back and forth between chat and emulator window in order to chat.
  • You will hear no sound while the window is unfocused.

If using the updated P2P client[edit]

Review
PROS
  • Excellent connectivity between 2 players (ONLY), sometimes informally compared to GGPO's netcode efficiency.
  • Basic chat support.
CONS
  • Requires port forwarding
  • The highest ping that it tolerates is around the 150ms mark, after which it starts to desynch very often
  • It's slightly prone to freezing/crashing/BSOD, but to a much lesser extent than the multiplayer client
  • Everyone needs to have the exact same ROM version and save file. Or else, it'll desynch or outright not work.
  • Chatbox is an eyesore.
  • You need to constantly switch focus back and forth between chat and emulator window in order to chat.
  • You will hear no sound while the window is unfocused.
