Rocky on the GameBoy is a little more challenging than it's Nintendo GameCube counterpart.
Just like the Game-Cube version, you relive the moments from the first five Rocky films.
Game play:
The overall game play is actually a little more challenging than the Game-Cube version. There's mostly blocking when you're in the ring and after the guy throws a punch, there's your chance, punch him. During story mode, you wrap up on experience points with three modes of practicing boxing: Punch Pads, Heavy Bag and Speed Bag.
Graphics:
The graphics look just like the Game-Cube version. The crowd in the background does not move that much, but that's alright. The cut-scenes tell a little more detail that the Game-Cube version forgot like mentioning Rocky's brain damage, Apollo training Rocky, and some more.
Controls:
D-pad for moving. A and B for punching. There's also some combos you can try out.
Music and Sound:
Music sounds pretty good and just like the Game-Cube version, it has "Gonna Fly Now''. Sound effects are pretty good too.
Lasting Appeal:
It's just as good as it's Nintendo Game-Cube counterpart and it's a little more challenging. 9 out of 10.
