- Back to: Sonic Advance 3.
Collecting more Rings gives the player more air control and acceleration, but the strength of the effect varies by version. In the North American version, this effect is far less significant compared to the Japanese/European versions and Sonic Advance 2.
Control is locked from the player after defeating a boss. For the Egg Hammer 3, Egg Ball No.2, Egg Foot, Egg Cube and Egg Gravity, the player regains control about 1 or 2 seconds after Dr. Eggman has left the screen in the Japanese and European versions, while in the North American version the player regains control immediately when he's off the screen.
This corridor, found near the beginning of Toy Kingdom Act 3, has two power barriers in the North American version. The leftmost barrier is not there in the Japanese and European versions.
The last Chao in Cyber Track Act 1 is surrounded by two barriers. In the Japanese and European versions, the barrier to the right is not a power barrier, meaning the Chao can be collected with any team. In the North American version, both barriers are power barriers, thus Knuckles is required.
Due to size constraints, the game features only one voice track on the cartridge, depending on the region. Western versions have English-language voices while the Japanese version contains Japanese-language voices of the main cast. The in-game text is entirely multi-lingual and is manually selectable in all versions.
Two sound effects are different between the Japanese and Western versions of the game. The sound effects in question being the pulley sound in Route 99...
...and the sound of a rocket exploding in Toy Kingdom.
