My biggest complaint is that their complimentary ROM collection doesn’t have any of the Patapon games. I put mine in and now it’s perfect :D

By outright piracy ofc. They include a shoddy SD card full of ROMs, but you can and should use your own card (for longevity) with your own ROMs (for legal reasons…)

The R36S is a “dirt cheap” Linux retrohandheld you can get pretty much everywhere. No built-in WiFi though, which limits usability quite a lot.
