Future Plans

  • Please understand that most of the updates may never come.

  • Cleaning the code to improve engines and save a lot of space.
  • Implementing a totally new engine using backgrounds and data.
  • Remaking all background and sprite sheets so we have everything we need for World 1.
  • Improving Mario's physics and animations.
  • Adding more title screen animations. Trying to figure out how to make the animations not take 300+ lines.
  • Completing World 1-1.

  • Adding enemies.

Alpha 0.6

  • Fixing all kinds of bugs you guys will find for me.

Alpha 1.0

  • World 1 should be done.

Beta 1.0

  • World 4 should be done.

Final 1.0

  • I wish the game could be the same as the original NES game, even if it can't be.


Only scan one version! The files don't have the same names between versions. I greatly recommend you to scan the latest version, which is obviously better. Have fun! SMB3 vA0.2

SMB3 Alpha 0.1


  • Q: Why am I stuck in the middle of the first stage?
  • A: I haven't programmed the whole stage yet.
  • Q: How can I help?
  • A: Unless you can help with things I ask for in the Notes section, you can't help, sorry.
  • Q: I can't read the QRs! / QRs are missing!
  • A: It's your problem, don't ask me about that. (Hint: Click on the pic to zoom!)


  • If anyone wants to help, I need the sound effects.
  • I'm not going to bring this game on SmileBASIC, because now there's upload copyrights.
