You can't stop the Blue Bomber's exploits on Virtual Console, as ESRB has rated Mega Man 5 for North America.
Interestingly there's no PEGI rating for the game yet, indicating this may be one of the few Virtual Consoles titles to hit North America before Europe.
The ESRB makes what was once the pinnacle of intense blasting action sound as exciting as a trip to the cracker factory:
This is an action-platformer in which players control a small character that shoots and jumps its way through sci-fi environments to defeat enemy robots. Players can use an arm cannon to shoot tiny pellets at enemy creatures (e.g., mouse-, bird-, and bug-like robots); effects include small white bursts and brief explosion sounds.
Those tiny pellets are bullets, guys.
