great I was of help to you guys. I’m a noob myself, just got my pi 4 days ago and been mucking around with it since then, every spare minute I have. I wrote my instruction out of my memory with a bit of googling for the commands/paths.

as for your other questions, sorry but that’s something I don’t know about, but I think it is highly unlikely.

one more thing you guys should know as well. you are able to save during the game and load if needed. all you need to do is add some more lines to retroarch.cfg, here is the exceprt from my file

savefile_directory = /home/pi/RetroPie/
savestate_directory = /home/pi/RetroPie/
#Save State: L2 + L1
input_save_state_btn = “4”
#Load State: L2 + R1
input_load_state_btn = “5”

whenever your button defined in input_enable_hotkey_btn is being pressed followed by input_save_state_btn you make a save state, whenever your button defined in input_enable_hotkey_btn is being pressed followed by input_load_state_btn you load the last save state
