well, if it's anything like the original nes mini, you can delete the original games, but by default hakchi saves them to the console. whenever you reflash the console with new games, everything is reset except for maybe game saves (can't remember), but retroarch is reset that's for sure. there's enough space on the original at least to accommodate all usa roms on the internal flash, can't say the same for the genesis or snes minis. both require an otg adapter.

first, i have no idea if it's like the original nes mini. Secondly, ....reflash the console with new games..... how do you even do that?
