Nein, lohnt sich nicht. Ich hatte ihn für ein paar Wochen und war sehr (!) enttäuscht. Liegt aber nicht an der Hardware sondern an der Software. Besonders DC ist ein Reinfall: https://marc.tv/recalbox-odroid-xu4-vs-raspberry-pi-3/

C'était avec la version 4.0.2 mais j'ai eu tellement de problèmes avec les manettes que j'ai refait une installation, suis passé à Recalbox 4.1 et depuis les manettes et le stick marchent bien.

Well, I feel a little silly, but I figured it out. The issue persists with my xbox controller, but I figured out why the ps3 controller wasn't wanting to work. I had the p1 controller set to default like the rest of them, which defaulted to the xbox controller which only worked when I replugged it in.

When I set p1 controller to the ps3 and p2 to the xbox, things are working well enough. The ps3 controller works in games, but the xbox controller still needs to be replugged (I may not use it much from now on anyway)

Sorry for the confusion, thank you.
