Keyboard works, but a lot of keys overlap with RetroArch shortcuts. In the latest version the keyboard has been disabled and only the retro joypad works.
A retropad can be plugged in port 1 (with or without analog stick).
In order to have a better experience with the keyboard, one should probably enable *Game Focus Mode* (normally Scroll-Lock) to disable hotkeys.
Video works, but the vertical flip is done in software.
