Q: Hi team, I have a bar top arcade with a Raspberry Pi installed. A friend messed up the button settings. Needs a reset or re-programming of the key functions, hot keys and so on. Something you can assist with? Thanks Steve

We can look at it. Most bar top arcades with a Pi run RetroPie, Batocera or a similar setup built on EmulationStation, and button mapping lives in a couple of places. There's the main controller configuration, which sets what each button does in the menus, and then the hotkey and per-emulator settings that change things inside games. When someone remaps things, it's often the hotkey button or a per-system config that got changed, which can make the whole cabinet feel broken. If you want to try first, most of these setups have a configure input option in the main menu that lets you map the buttons again from scratch. Back up the SD card before changing anything, since that card holds your games and settings. If you'd rather we handle it, order the free Raspberry Pi diagnostic, describe the setup in the order notes, including the software and button encoder if you know them, and ship the SD card with the Pi. We'll quote the reconfiguration before doing anything.
