I didn't find any threads for this in the search engine, so here's this one! Talk about the GB Megaman games.
I just downloaded MMV today on the 3DS VC, and it's a TOTAL BLAST! I don't know anything about the game, but I took Neptune down first, and I took no damage. He and his stage were quite easy. I took on Mercury next, and the difficulty suddenly escalated a fair amount. Gonna leave the rest for later, but so far, this game's great.
