0102C1C1 Walk Through everything. It should be used with the always
be Super Mario code. If you need to go down a pipe turn off the codes and
get hit, you will then be in normal mode. You must turn the codes off
before you try to hit a pole or you will get stuck. Also you will need to
turn off the codes and get hit by Bowser before you can get the axe.
I recommend this code only for Levels 8-1 through 8-3.
01FF8EC1 + 01FF8FC1 + 01FF8FC1 + 01FF91C1 Activates all challenge
levels. Codes must be off to start the game. Go into a level and turn on
codes, then save. You will then be able to do any challenge level.
010392C1 Activates the Lost levels and Boo vs Game. Enter code then
go into a level turn code on. Save and end level. You can now click on Luigi
and play the Lost levels.
01FF29C4 + 01FF2AC4 + 01FF2BC4 + 01FF2CC4 Activates all pictures.
Follow above instructions.
