I now have my own version of cps2emu in the extra-devel repo: cps2emu-ng (based on the code of 0.6-r1).
Cps2emu-gui 0.0.1-5 and higher will depend on this package and cps2emu-ng will conflict with cps2emu (so that has to be uninstalled).

I made my own key configuration in cps2emu-ng, now also including bindings for for example exit and menu. It is based on the ASCII/SDL codes, also to avoid language issues, and Cps2-gui helps you with it

Sixaxis default config is no longer activated in cps2emu when a connected joystick is detected, but has to be set checked in the config.
