With the Fire Shield active, Tails will fly very far up until his AI forces him to return. The chance of this happening slightly increases if the player has an elemental shield.
If the player holds the up button on the D-pad with Tails standing next to them, jumps, and uses the Insta-Shield, Tails will sometimes use his flying ability. Activate Tails's flying ability with Sonic & Tails:.Once there, they must continue forward until they get to a section where there are circles dug out of the ground with spike balls spinning around in them.The player should then push against the spike ball in the direction opposite of the one it's traveling in, and the character's sprite will then turn upside down. Just before a checkpoint, there is a switch which the player must fly/jump over to land on a raised ledge. To perform this glitch, the player must be in Flying Battery Zone Act 1 as either Hyper Sonic or Super Tails, and travel to a point after the first magnetic section with 2 moving cannon type robots. So when the player goes above the camera, it causes in a integer overflow, resulting in a very large positive number (65,535), so the camera rapidly moves to the players current position, and while in this state, all sprites are unloaded, allowing the player to move into them). This can be used to skip over bosses, return to the beginning of levels, and to go past the Knuckles-only walls in IceCap Zone Act 1 as Sonic (This is caused because the stage is so tall that it vertically loops infinitely, and instead of the stage's 0,0 in pixels being in its normal position (at the very top left of the stage), it is instead locked onto the camera. To perform this glitch, the player must press and hold down until the screen moves, then jump. This is also possible if the player enters a Bonus Stage. If the player enters and exits a Special Stage, the Zone's music would automatically change to Angel Island Zone Act 2's theme, although the title card states that it is still Act 1. This bug/glitch can be found shortly after the first encounter with Flame Craft. Many of them have not been confirmed by Sega. Unless otherwise noted, all glitch names are conjectural.
