Powkiddy V90 aka Anbernic S-100 is my currently my favorite pocket gaming device! Soon there will be an updated community firmware that brings a lot of new exiting things! My contribution to the new firmware are emulators for Commodore 64 and MSX. But it does also run DOSBox, Game & Watch, NES, SNES, Sega MS & MD, Gameboy Advance, Lynx, Spectrum and many more. I recommend buying it from Bangood.
