nothing
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.
get a action replay ds put it in then put the game in the replay then find the cheats 4 that game and put inviciblity 4ever or just invinceibility i think
you can buy them at gamestop
I dont think there are any action replay invincibility codes for Super Mario World on gameboy.
its probaly because it is not saved on your action replay.
there IS not a code to play as Mario
