The Complex Code of Mega Man 2 and How Zipping Works

I’ve released a new video that focuses on the horizontal movement of Mega Man 2 and environmental collision detection.

The game was coded in a way that allows Mega Man to move forward – but – constantly adjusts his position so he doesn’t end up stuck in a foreground tile. The problem is that this logic is broken! Speedrunners use the bug to move through the levels by zipping in applicable areas.
