Wee, thought someone might want this.. I've been playing this game non stop I just beat Bowser at the end I beat every world I did skip a few levels here and there but I beat every world.
This save state is after bowser and at a World Selection Screen anyways if you want to download it here it is.
It's for Visual Boy Advance
Make sure your game and this save are the same title before using! if the game is named mario (j).gba make this save mario (j)1.sgm when visual boy advance starts up hit "F1" the save will load.
Enjoy...
