Drastic stuff? Can you just specify a bit? :o
(The very thought of two guys lovin' each other ridicules me for some reason, actually. >_>)
GBA. There are some Megaman games available for DS too. Though, you'll find most of the games to be utterly difficult even at normal difficulty settings. If you're a 'first-timer' then you may find the normal difficulty settings too high. Though, you won't have a chance to play in high difficulty settings before you beat the game at normal settings.
Here's a pic of Zero. (OMG, I <3 his character design!)
