V2s are better because of the shop - but wouldn't you swap Bump with the old V1 Hurdles/Jump or Dance? I miss having them on my V2 (and I hate that I always lose at Bump in the first or second round)!
Of course!! Go into the shop... Press the 'A' button several times untill the shop keeper looks surprised... then enter the code!! Repeat for all 5 codes... Hope I helped... h34r:
