  • SZLIVO - Mario or Luigi will start out small. If you have any experience with the always stay big code, you will know that it does NOT work until you get a Super Mushroom. With this code, once you get big, just as with the always stay big code, you will never die unless you fall in a pit or run out of time. However, you do not stay big! The first time you die, you will change from big to little, as usual. The second time you die, you will change from little to big. Other cool things you can do with this code:
    • Have fire power when you are small.
    • You don't lose your fire power or invincible power when you die from enemies (that is when you change size). You do, however, lose those powers when you fall in a pit.
    • Easily change size just by killing yourself.
  • PIGPOG - This is a really great Game Genie code that results in all sorts of fun and random errors, but the graphics remain clear and normal. Princess Toadstool as an enemy, Koopa on 1-1, Squids on land, etc.
  • GOZSXX - Invincibility from Everything including Lava
