Is your feature request related to a problem? Please describe.
I purchased a Funkey S for the novelty but never use it because I'm using RetroAchievements to structure my retro backlog, making other devices more suitable for play.
Describe the solution you'd like
I'd like a USB networking stack to be implemented so that when RetroArch is launched, it is able to fetch and cache the achievements, then sync those achievements back at the end of the play session by plugging back in before closing the device.
Describe alternatives you've considered
I don't see any other alternative given the issue and the constraints.
