Features

• Button binding.
• Axis binding.
• Power saving mode*.
• Persistent config.
• "NoDefault" option to disable default Android key press action for unhandled keys.
• No accidental config resetting via recovery-style "yes" selection.
• Autoconnect option on program open.

User guide

Input Redirecting to your controller

• Connect your controller to your android phone in whatever way works (usb or bluetooth).
• Install and start IRdA on your phone.
• Check CAL Button and map your controller to the 3DS inputs. Uncheck it when completed.
• Check CAL Axis and bind the analog sticks axis. Cicle Pad is left stick. C-Stick is right stick.
• Start input redirection on your 3DS. Enter Rosalina menu on your 3DS (L+Down+Select) > Miscellaneous options > Start InputRedirection.
• Press B and take note of the IP adress on the top right of your screen.
• Press input IP address in the options in IRdA and write that IP address (both should be on the same network). Select Commit config.
• Exit out of rosalina and you should be able to control your 3DS with the controller.

Retroarch Multiplayer

• Go to settings and input. Scroll down to User 2 and set device to 3ds. Use the latest stable retroarch.
• Start any game with the emulator you want (snes9x2002 has issues with input changing).
• Go to quickmenu and controls. Go to Player 2 and set the corresponding left analog axes as dpad directions.
  • Remember how you mapped your controller earlier and scroll down and set L as A and R as B etc.
  • Then set Left Analog as the dpad by mapping the respective direction.
  • The person using the controller will have to use the analog stick for movement, because the 3DS' Circle Pad won't work as long as it is receiving input from a controller.
• Make sure two controllers are connected for the system you're emulating. Sometimes this is in quickmenu options (i.e. pcsx_rearmed) other times in controls.
• You should be ready to play.
