List of glitches
In Neo Green Hill Zone, sometimes when running down the large hill as Amy with the Lightning Shield, she'll fall through the ground and die.
 * Amy through the floor:

When climbing a wall as Knuckles, if he is crushed by a moving block at a right angle, he'll be either pushed above or below the block and off the wall.
 * Pushed off the wall:

Players using Sonic, Knuckles, or Amy can crouch near certain loops with their back to them, wait for the camera to go down and move with the camera locked on that position, causing the map to lose its solidity. This can be reverted by triggering a path swapper, which is not easy to do with the ground not being solid as a result of the glitch. This glitch is useful to time attack Angel Island Zone Act 1 as Knuckles. The Acts affected by this glitch are Neo Green Hill Act 1, Secret Base Act 1 and Angel Island Act 1.
 * Path swapper glitch:

The original releases of Sonic Advance in all regions have a rather severe bug: deleting the main game's save file does not delete the Tiny Chao Garden data, but once the player does so, Rings earned in the main game do not transfer over to the Tiny Chao Garden. There are two ways to revert this; either the player must use a video game enhancer such as GameShark, or collect the same number of Rings that had been collected before the game data was deleted. This was fixed in v1.1 (only released in Japan), and in the Sonic Advance and Sonic Pinball Party combo pack.
 * Tiny Chao Garden ring transfer error:
