Collectors of retro games will know this fact all too well; many RPGs from the ’80s and ’90s are now practically unplayable, as it’s impossible to save your game (unless you’re willing to crack open the cartridge and replace the battery, of course).

For one Super Famicom fanatic, known as Wanikun, the thought of losing his save file for Umihara Kawase was simply too terrifying to comprehend, so he decided to keep his SNES console switched on for 20 years in order to preserve it.

Wanikun posted this statement on his Twitter account.

The game - which has recently received a sequel on the 3DS - launched in Japan in 1994. Wanikun’s console has been turned on constantly almost since launch, with one exception - it had to be unplugged for a house move, but amazingly the battery still had enough juice to keep the save file intact. So while it technically wasn’t a full 20 years, I guess we’re going to let it slide.
