Cabinet-Friendliness Tips

Reassigning Inputs

While any game is running in Mednafen, press ALT+SHIFT+1. This will prompt you to set and confirm all of your inputs for player 1. To set up player 2's controls, press ALT+SHIFT+2 and repeat the process. This will commit the mapped inputs for the current game's platform.

Alternatively, you can edit Mednafen's config file in a text editor. Open ~/.mednafen/mednafen.cfg. Scroll down to or search for the platform (e.g: ";nes", ";sms", ";gba"), and set the desired keycodes for your inputs.

Example:

  ;nes, Port 1, Gamepad: A
  nes.input.port1.gamepad.a keyboard 122

Reassigning Save State Keys

The number keys are used to select save states. If you have 1 and 2 mapped to your start buttons and you want to disable the save state messages that appear when you press them, you will need to remap the save state keys. Scroll down in the mednafen.cfg file to ";Save" and make the following changes:

  ;Save state 1 select
  command.1 keyboard 0
  
  ;Save state 2 select
  command.2 keyboard 0

Now you can map player 1 start to the 1 key, and player 2 start to the 2 key, without conflicting with the save state selector.

Sound

If you are having sound issues set the following in either the ini or as commandline argument

-sound.device                     	"sexyal-literal-default"

Exit on ESC

ESC exits the emulator by default.
