Rockman 4 Minus Infinity - Wily 2 (Gradius II - Overheat)

This is a level where you kill a bunch of enemies on conveyer belts and then get sucked into a Gradius level. Then Dr. Wily makes a dark clone of you that stands on the ceiling and takes four of your weapons with the patented Dr. Wily Stealing System. But it’s PureSabe, so it’s manageable.
