10:52 I don't know why, but this made me chuckle like a ninny. I know it's just random hexadecimal, but the fact that it just so happens to spell "BOB" is hilarious in a way I can't quite describe.
I should mention that some of the Angel Island 1 crashes can be avoided by waiting for long enough so that the water level drops down. If you wait just the right amount of time (I believe 9 seconds), the game will survive, but will freeze for several seconds, then you will instantly lose a life (unless you use Debug Mode to interrupt the death sequence). If you decide to continue forward after letting the water drop without losing a life, you'll see that a good amount of corruption occurred.
Really good video, you should do more like this. Then once those videos are popular, do a version where you fully explore the glitched levels with debug mode.
