More from Skawo: Demonstrating a NES’s Failing PPU

We linked to a Skawo video yesterday, the one about flash card rumble motors activating when playing Link’s Awakening DX. Well I happened to have this one open, so here’s another: the last gasps of a failing PPU chip, shown off in several games. (5½ minutes)

It starts out seeming to work okay, but it isn’t long before it becomes obvious that something very wrong is happening. If you ever wondered what a failing graphics chip looks like, well, this will show you one example of it happening. Chips can fail in any number of ways, and there’s no guarantee that another PPU in the process of expiring will expire in the same way, but this is the kind of thing that can happen.
