Notice: The preceding cheat codes, hints, tips, walkthroughs, unlockables, easter eggs, FAQs and secrets are currently all the game help that is in the cheatboy.co.uk database for Sonic Advance 3. Because Cheat Boy does not have every game for Nintendo Gameboy Advance, it is impossible for use to check that every cheat on our website is correct. Also, for a small minority of games, it is the case that some of the cheats and tips listed above will only work on certain version(s) of the game, as occasionally the PAL, NTSC and Japanese versions of a game will not have the same cheats. It may also be the case that some cheats may have an undesired effect on your game which we do not know about yet, so it is strongly advised that if you can you save your game before using any of the cheat codes and other tips on this page.
