@mitu I see thx, so do you think this is very specific or maybe more common and with more roms? or do you even know of a compatibility list of lr-gpsp?

@thelostsoul

I don't know the full extent of the problem, but it seems like you could create a script that would first launch RetroArch and then after a wait, send a network command to load the game. You could then create a launch command in /opt/retropie/configs/emulators.cfg that would launch the script and apply it to the ROM. Granted, this is a very involved solution and there might be a better way. Out of curiosity, why are you opposed to simply launching the games with a core that will run them?

You need to exit gpsp from the menu with "Exit gpSP" after configuring controls, not by pressing exit etc.

This is of course documented in the wiki. https://github.com/retropie/retropie-setup/wiki/game-boy-advance#gpsp

ZIP files cause headaches on some emulators that may or may not support the specific ZIP format that archive is in, so to avoid any ZIP issues I have unzipped ALL archives so that the ROM is there for the emulator to load without having to spend extra time extracting the ZIP archive to a temporary file then loading that. This all causes emulator slowdowns, even just a small one it all adds up, plus if you're using purely an SD card or USB pendrive to run everything from it will be even slower. Also an increased risk or SD card corruption with all those read/writes on an SD card

The only archives I leave alone are the arcade ones, these MUST be left zipped or WILL fail. MAME, FBA and NEOGEO are the main 3

I use OSMC with KODI and RetroPie so have it run everything from an external USB hard drive, the only function the SD card performs is booting the PI 3 B I use at the moment then control is passed onto OSMC which runs off the USB hard drive so being much faster and much less chance of SD card corruption. I know thats not possible for everybody especially if you have a portable RetroPie in a handheld where space is very limited
