what i did is going for the smallest sd card, and buy a proper bigger one, then clone the “stock” card, and copy over roms and metadata from my nicely curated Batocera drive.

it can be super tricky to get any OS that officially supports the R36S to run on the clones, so i run the OS it came with. the device isn’t connected to the Internet so i don’t worry too much about malware.

dreamcast is simpler to emulate, n64 notoriously isn’t, I’ve been struggling with this system during my Raspberry Pi 3 emulation era already. the “real” R36S apparently is a tad more powerful than the cheap knockoffs, but i can’t seem to find it anymore - the closest available official one would be the RG35XX for $55
