Emulator: BizHawk version 2.7
ROM version: Rockman Megaworld (J) (alt 1)
This file starts from a save state because it's from my full file after the Mega Man 1 credits. Thus the actual run time of this run from power on would add about 224 frames total.
The two notable problems with this collection are the lag problems and the weapon timing differences. It's more significant here since enemies have notable i-frames of at least 9-10 and rapid fire at best is a shot every 9 frames. This makes shooting and moving more complicated as shooting at the absolute fastest rate means some shots get ignored. There are also notable sections that add tremendous lag from things like being airborne and shooting weapons at certain points. The alien fight in particular is a nightmare since the game slows down by half if a bubble shows up for more than a frame at a time, complicating the already troubling rapid fire problem.
Approximate final time from "power on" to final input: 102326 frames, or 28:27.632
