2 0 0There are 2 ways to do this. Offline versus, but you'll need a second controller. Otherwise you can do it in arcade mode. Which stage you get the mirror match depends on which character you select. Every stage will be the same opponent.Stage 1: KnucklesStage 2: AmyStage 3: BarkStage 4: EspioStage 5: TailsStage 6: FangStage 7: BeanStage 8: SonicSince you'll have to play through the 1st 7 stages anyway for the other trophies, it really doesn't matter who you select since you'll be guaranteed a mirror match anyway. Just don't use Honey the Cat, since there will be no possible mirror match for her. Obviously the quickest choice would be to use knuckles.
