Zipping
A-Trigger vs. B-Trigger
Several zips will refer to an A-Trigger or a B-Trigger.
A-Trigger zips require mega Man to be in position in the ceiling (or above the screen). The player then jumps (pushing A), and then 4-to-7 frames later, tap left. (NOT A+Left at the same time, but A-Then-Left)
If Mega Man is off screen, such as the Heat Man Zip or most beginner Bubble Man Zips, you must use the A-Trigger.
B-Trigger Zips use Mega Man's "throwing" animation, and tap left during the animation to trigger the Zip. Most Screen 2 Crash Man zips, and the Metal Man Zip use the B trigger.
Ladder Zips
Just like Mega Man 1, Mega Man can climb too high off a ladder and end up in the ceiling. This can cause Mega Man to zip.
- As part of the "Good Wood" zip
- As "The Sexy Zip" on screen 2 of Wily 4, and several other locations in Wily 4
- There are at least 2 locations where this can Zip the player into a bad situation, so use caution when grabbing the top of ladders.
- Wily 1 vertical section near the Sniper Joe
- Wily 4 screen 3
Vertical Screen Zips
The easiest one of these is probably in Wily 4, the screen with two false floors and a ladder up to the screen with a false floor above spikes.
By riding the item 3 next to the ladder until Mega Man pops into the ceiling, then pushing jump 3 times then up+left. Mega Man appears on the next screen at the very top, not needing to navigate the room.
This occurs in a few other places (the end of the first screen of Wily 1, the middle of Good Wood).
