The classic RTA route for Mega Man 2 zipless. It turns out it's way faster to use Item 1 in Air, even though almost every other stage becomes slower in the process.

Compared to v2.2, I saved a bit of time with an early switch in Metal, which broke the frame rule. This time was ultimately lost in Bubble due to bad RNG. I did some more optimization and cleanup, which saved no time.
This is not the perfect version of this route, though. I've saved 58 frames in Crash due to optimization and better understanding of offscreen ladder grabs. There's no real reason to apply these improvements to an obsolete route, so I'm not going to.
