Similar to other variations, Sonic Advance (J)(Independent) is potentially a ROM hack or independently distributed version of the Japanese release of Sonic Advance. The 'Independent' descriptor suggests it wasn't officially published by Sega. It likely retains the core gameplay of the original, though elements may be altered by the creators of this version. The game stars Sonic, Tails, and Knuckles in classic platforming action.
