Controls

RetroArch Hotkeys

Button Combo Action
SELECT+START (x2) Quit Game
SELECT+R1 Save State
SELECT+L1 Load State
SELECT+Y(NORTH) Open RA Menu
SELECT+X(WEST) Show FPS
SELECT+R2 Fast-Forward

Notes:

  • By default ROCKNIX will detect your controller and configure RetroArch hotkeys automatically. This is controlled by the "AUTOCONFIGURE RETROARCH HOTKEYS" option in the Settings > Controller & Bluetooth menu. While the option is enabled, RetroArch hotkeys will be overwritten by the above defaults each time RetroArch is launched. If this behavior is not desired that option can be disabled and your user-defined RetroArch hotkeys will be used instead.

Mednafen Hotkeys

Button Combo Action
SELECT+START (hold for 2sec) Quit Game
SELECT+R1 Save State
SELECT+L1 (hold for 2sec) Load State

Notes:

  • By default ROCKNIX will expand the configuration file according to the first controller mednafen finds. This only happens when the config file doesn't exist (meaning the first time or if you manually delete it). After the initial expansion you are free to customize the controls.

HDMI Output

Press L1 + START + SELECT while in EmulationStation to swtich between Screen and HDMI output.

While this should work; it doesn't always result in the correct resolution. The best way to get consistent results is to turn off the device, plug in an HDMI cable and reboot.

"Why doesn't hot-plugging just work?"... Hot-plug HDMI switching is a fairly complex action to accomplish and not something we have implemented on any device. If you are a developer and interested in helping to build this functionality please start here: Contribute
