It depends on what system but for the DS you can
Action Replay codes might help
The best thing to do is to just get an action replay.
No, sorry. I had AR (Action Replay) and I went through website by website and found nothing with Baby Mario.
you can buy them at gamestop
I dont think there are any action replay invincibility codes for Super Mario World on gameboy.
You actually can't really become Mario in the game without editing sprites, which are the pictures you see in the game such as the Pokemon and the players, including yourself.
its probaly because it is not saved on your action replay.
there IS not a code to play as Mario
