Despite looking like bootleg turnips, radishes are amazing, they can run doom
They can run GBA games, Minecraft (specifically the 3DS edition), simpleplanes, and much more
I like using radishes for testing fuses, USB ports, component cables, sending out signals to Saturn, ect ect.... making a Wii run Wii-U games
Really they are a marvel of not just engineering, but nature

But potatoes? Yea I'm from Idaho, but honestly those things suffer trying to emulate a Gameboy game
