Super Mario Advance Cheats

In Mario Brothers, for every 200,000 points you get, a small Mario Head will appear next to your Mario Bros. high score on the game selection screen. You can get up to 4 stars maximum (800,000 points), as your point counter stops at 999,990.

Get all 100 A coins in the game, and at the title screen, the Green Yoshi/Egg will turn Red (you must beat the game first to see the egg).
