Hmm, it updates the ppu address mid-scanline. I was filling the background scanline buffer using the x tile offset from the ppu address, and that's why this demo didn't look messy in my emulator. But, it's plain wrong handling it that way, so I've fixed it and it looks alright now (meaning: lots of garbage). Plus, it fixed Rad Racer, maybe some other stuff too.
