One brilliant modder has made a Game Boy Advance SP for the end of time. Redditor u/Bangooh created a Franken-SP attached to a DeWalt XR FLEXVOLT power tool battery. Essentially, a retro handheld that could fit into a contractors tool box instead of a toy chest.
It’s ridiculous, rugged and based on commenter’s guestimates, should run continuously for approximately 17 days without interruption.
Yeah but can it drill holes and stuff?
