SDL MAME Wii is an Arcade Emulator based on SDLMAME. Many games for early arcade boards can be played with varying amounts of success.

How to use

Unzip onto your SD card/USB drive.


The controls are configurable in the emulator itself or by changing the settings in /mame/cfg/default.cfg file. Below are the default control settings:

GameCube Controller WiimoteHorizontal.svg Wiimote.svg + Nunchuck alternative.svg Action
GameCube L Trigger Wiimote HOME Button Wiimote HOME Button Emulator Menu
GameCube R Trigger Wiimote - Button Wiimote - Button Insert Coin
GameCube START Button Wiimote + Button Wiimote + Button Start (not all games use this)
GameCube D-Pad Wiimote D-Pad Wiimote D-Pad + Nunchuck Control Stick Up/Down/Left/Right
Gamecube B Button Wiimote 1 Button Wiimote 1 Button Button 1
Gamecube A Button Wiimote 2 Button Wiimote 2 Button Button 2
Gamecube X Button Wiimote B Button Wiimote B Button Button 3
Gamecube Y Button Wiimote A Button Wiimote A Button Button 4
GameCube Z Button Wiimote + Button + Wiimote - Button Wiimote + Button + Wiimote - Button Back (Exits current game)


  • Lots of ROMs are supported, but not all of them. If you don't see the ROM in the list in the emulator, then support for that ROM isn't included. This is to keep the size of the emulator low enough to run effectively on the Wii. A list of all the ones that are can be found here:
  • Just because a ROM is supported does not mean it will run. Even games for early boards like CPS-1 can fail to run due to RAM limitations. If the emulator suddenly kicks you out to the Homebrew Channel, look in the MAME folder (sd:/mame/) for a file called errors.txt. If it says something about failing to allocate space, then odds are the ROM can't run on the Wii. The emulator might also crash outright and leave you with a code dump if RAM runs out.
  • Because the Wii is not a strong console, some games will be slow. Frameskipping is enabled by default to make games playable.
  • The joystick on GameCube controllers can't be used.
  • The default controller mapping is unsuitable for lightgun games, but there is currently no way to make seperate mappings for lightgun and non-lightgun games. If you wish to change the configuration for lightgun games, replace the default.cfg file in mame/cfg with the default-lg.cfg file included.
  • On older TVs, the edges of the screen can be cut off. To fix this, in mame.ini, look for the option "safearea" and set the value to something around 0.8 and 0.95. It will vary depending on your TV.
