Super Nintendo consoles appear to be running faster as they age, with the APU's processing speed increasing over time, though the impact on gameplay is minimal.

The legendary Super Nintendo Entertainment System is 35 years old and still a mainstay in every classic gamer's heart. It's also much beloved by the speedrunning community, which has found itself in a bit of a quandary recently—as it seems the elderly console might run slightly faster as it ages.

Most hardware breaks down and gets worse as it ages. Some old Super Nintendo systems, however, are actually running faster. The changes aren’t noticeable to your average player, but dedicated fans have been measuring the differences and trying to uncover why the changes are occurring and what it could mean for the speedrunning of classics like Super Mario Kart and Super Metroid on original hardware.
