Text Zip

A text zip is a glitch that happens when you trigger a text box on the same frame as triggering a screen transition. The effect is that the screen scrolls twice instead of once, and then scrolls back once. After it's all done, you end up just less than 1 screen width away from where you should be.

This glitch was discovered by accident in Chikakoo's 29m37s 100% speedrun in January 2017.
