Which old Megaman game?

[mirror's edgy]

I lucked out and bought a wii with 500 wii points already on it, and I am curious about the blue bomber. Megaman 1 through 4 are available for 500 points and I'm wondering which to get. I'd rather get something easier, and at the very least, something with many continues or passwords.

They all have infinite continues, but the first one doesn't have a password system. I sugest that you take the second one, it's the best one...
