    How to play
    1. There is no build to download: get the code from the project's repository.
    2. Build it as its README says. What the build gives, a program to run or the original game rebuilt for an emulator, is written there too.
    3. The project's page says what it needs from your own copy of Sonic Advance 2, if anything.

From SubmitGame's list, read Oct 21, 2026, with releases, stars and licenses as each project's repository gives them. The steps are the same for every project of a kind: its own page has the details.

Under the hood: every project behind it, its license and code, how they connect, and who made them.

About

Sonic returns for a second outing on the Game Boy Advance. Once again, Sonic is called upon to save the world from the evil Dr. Eggman. On this occasion, Sonic is joined by friends Tails, Knuckles and Cream the Rabbit, the latest addition to the Sonic team. Each comes with a set of unique moves, allowing you to reach certain areas through-out the levels. However, unlike Sonic Advance, you must complete the game as Sonic to unlock the other characters. Chaos Emeralds and Special Rings litter the stages. To collect the emeralds (transforming Sonic into Super Sonic for the final battle with Dr. Eggman), you must find the special rings hidden in each stage to unlock the bonus stage. Complete the bonus stage and the emerald is yours. You'll also get the chance to collect and raise chaos, and trade them over to Sonic Adventure 2: Battle on GameCube, through the use of the GBA/GC link cable.
