C:Mid Jump|01070AC2|pmp2000|With this code you can jump in mid-air if you walk(not jump) off a ledge.  Also, if you use this code with the "Walk on air" code, you can slowly float up.

C:Wacky Speed Mod|01??0EC2|Pika98765|00~04 are normal speed. 05~7F are super mega turbo. (So fast the game's scrolling can't catch up, and you usually get stuck in objects. Also, you'll never finish the level.) 80~FF Are super mega turbo backwards. (Unlike in Mario DX, this doesn't change your direction.)
C:Helium Mario|010107C2|Pika98765|This is basically a slow moon jump. You can still walk while you float up. If you stay under an object, you'll eventually go up through it! You go faster if you turn it on while running. Change the value for other effects. 02 makes you fall through the floor and die really fast, and 04 makes you bounce, and float for a bit if you hit something above you. (My game crashed a lot when using this, but I think it was because I was accidentally tapping it.)

Apparently, you can only use levels from the current world. Also, you can turn it on anytime and have it suddenly start in the level you chose!
