I put the Crash Bomb between the 1st lamp and the wall. The explosion destroy both of them. The rest of strategy is still valid!
Result: 6 Shots, 1 more ammo.

Thanks, Man. Say, I would thank you for your help. Your Cool!

It is not bad,i kinda wanted to say that the game tryes to force the difficult with things that look unbalanced to me or something like that??

I find it easier to shoot the blinky in the centerish of the room second. The reason being is that it's easier to stand in the center of the room and dodge when it is not there, since the attacks shoot toward your location. It gives you more time between the time they shoot and the time you have to jump and clear them, making it more likely you can clear them. You can stay in this position and dodge while taking out the blinky behind the cage on the left. I think like to drop down and get the one in the bottom right before going for the one in the center right, because again, it's easier to dodge when you're down here. If you go to the one on the right above it first, it is impossible to dodge if the one below fires during that time. You have to consider the trajectory of the enemies. If you do it this way, it's pretty easy to clear the boss with only getting hit 1 or 2 times, even no damage if you're really careful with dodging.

MM2 has so many Horrible Designs (That Boss for example,and Quick-Man's level too)

This Mega Man Legacy Collection vanishes Mega Man a lot in this room, and at the Mecha Dragon boss, where there is heavy graphical break-up on Mega Man. I found it helpful to switch back to the default weapon (P) so that a weapon energy meter is not displayed.
