On the character select screen, highlight Sonic, then press Up Right Down Right L Right R Right A. A Ring sound will confirm correct entry, and Tails will now follow Sonic similar to how he did in Sonic the Hedgehog 2 and Sonic the Hedgehog 3.

SRAM failsafe

If the game fails to detect an SRAM chip (usually if the chip is not present or is faulty), all content will be unlocked. This is also the case for the other Sonic Advance games.
