The Super Nintendo is somehow getting faster with age.

We’ve come to expect reduced performance from aging hardware, but some gamers have discovered the opposite with the Super Nintendo, as spotted by Time Extension.

The SNES’ main CPU, featuring a quartz crystal, is okay. But the console’s audio processing unit, which uses a ceramic resonator, is now running faster and speeds up as the hardware warms. The issue will potentially produce higher pitched sounds, but it’s not yet known if it will affect gameplay.
