Alpha 0.3 Edit

  • Implementing a totally new engine made by GimmeMoreCoinz .
  • Remaking all background and sprite sheets so we have everything we need for World 1.

  • Probably going to fix bugs that will be reported in the comments.

Alpha 0.6Edit

  • World 1-2, and probably World 1-3 too.

Alpha 1.0Edit

  • World 1 should be done.

Beta 1.0Edit

  • World 3 should be done.

Final 1.0Edit

  • I wish the game will be 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: 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)


  • I need the sound effects.
  • I'll port the program to SmileBasic (Petit Computer 3) somewhere between Alpha 0.3 and Alpha 0.5. Afterwards, no more updates will come to the Petit Computer version. Due to SmileBasic's server upload rules, I am not allowed to port a Mario game on SmileBasic because of the copyright. That means this project will most likely be cancelled by the release of SmileBasic. Thank you for your understanding.
