Hi everyone, I bought an Ambernic RG CubeXX on April 28th and I'm waiting for it to arrive, it's going to take a while... In the meantime, I ordered a screen protector, a silicone case, and a hard carrying case. I wanted to know about micro SD cards and operating systems, which one do you recommend? I have two micro SD cards here, a 32GB Lexar and a 64GB SanDisk. Should I use both? I want to play more GBA, GBC, SNES, Pico games...
