I've installed the GUI and used it to create a keymap.
Thank you, Fötus.

Rollcage runs at full speed on ReArmed (1150MHz, no sound, frameskip 2), but the '-gles core crashes after a couple of seconds (maybe a mc-related glitch, as I'm able to enter the menu but can't get past it). Too bad, really, 'cause the '-gles core makes the game look great.

I can't wait till you manage to merge '-gles and ReArmed, bp
