This port of Super Mario Brothers 3 for the GBA is pretty solid overall. I like how they minimized the HUD to maximize screen real estate for the game. My only complaint with this is that the music is noticeably down sampled and sounds kinda bad. I'm sure that's just what they were working with on GBA. This is a no-commentary playthrough, enjoy the game without my banal yapping!
