    So, I'm messing around with PSX emulation on the RPi0 with PCSX-ReARMed because I'm interested in that RetroFlag GPi. Putting aside any issues that the case/kit might introduce, I want to see which games run at or close to full speed on a RPi0 with auto-frameskip on (turning off frameskip whenever needed if it causes extreme issues) and emulate well using just the inputs you would find on a SNES controller since that's all the GPi has as well.

    Right now, my problem is that PCSX-ReARMed doesn't have any hotkey support unlike the other standalone emulators of PiSNES, gpSP, GnGeo-Pi, PiFBA, and MAME4All. I've attached my PCSX-ReARMed config in case anyone wants to check it out and give me some shots in the dark as to how something like a button combo might be achieved within the emulator itself.

    All I need is the ability to map two buttons on the controller so that when they are pressed together they execute the Escape keyboard key: preferably only when PCSX-ReARMed is running, though I could remap the required keyboard key to something none of the other emulators would respond to.

    Would I be able to do the Button+Button=Escape using this? https://retropie.org.uk/docs/Universal-Controller-Calibration-&-Mapping-Using-xboxdrv/ Looks well written, but quite a bit of work so wanted to ask here before I threw my time into it.

    Thank you for your time.


    Update
    Investigating something called joytokey.py as a possible solution to this now. Seeing if this topic sheds any light on where to begin with the program: https://retropie.org.uk/forum/topic/19938/joy2key-py .
