V1.02 --Added Minus World
V1.03 --Fixed minus world bugs, completed scoring system, tweaked jump physics

This is a demo for my Pico-8 port of Super Mario Bros., and it includes all of World 1, along with the secret 'minus world'. I plan to reskin the game before a full release to avoid potential Cease-and-Desist letters, but wanted to give people a taste of it in its original form. Also, not everything is quite finished, and I figured this would be a good way to get some playtesting and feedback, so please let me know if you encounter any bugs.

Special thanks to:

  • Jwinslow23 for composing the music and many of the sound effects
  • Zep for his PX9 compression system
  • Thisismypassword for the Shrinko-8 minifier
  • Nick N. Bruns of NESmaps.com for documenting level maps

great port, feels almost just like the original

P#141382 2024-02-10 20:34

Thanks, I've spent a lot of time adding details from the original. The fireworks even go off if you hit the flagpole at the right times.🙂

just like the original. nice

P#141386 2024-02-10 21:54

It's pretty good. I feel like I'm making some jumps by the skin of my teeth (in 1-3) especially. Otherwise, a really good recreation.

P#141418 2024-02-12 05:28

Yeah, the physics could still use a little tweaking, I know Mario doesn't slide as far as the original when you duck. Thanks for the feedback!

This is incredible! There were a few times I forgot I was playing a pico-8 game, with the only thing reminding being the Visuals and Audio! Now, I do notice the Physics are a little bit different, which there is a pretty good write-up on online if you go looking, but it's not bad for what it is and plays great! It wasn't like I didn't know if I could make jumps or whatever.
Can't wait to see more of this!

Thank you very much. I put more of a focus on getting everything working than exactly mirroring the physics, but I'll look and see if I can find some better info on that to tweak things. Just uploaded a new version that fixes a couple small bugs.

There is no -1 world. :(

P#141523 2024-02-15 15:38

I like this better than the other one that zooms in on pico-8. Good job!

P#141527 2024-02-15 16:26

Well, I made all the code for this from scratch, so it doesn't work the same way or have the same glitches as the original, but I'll try and add a version of minus world.

Thank you, glad you enjoyed it.=)

Pretty good recreation. Better then many I've seen on Pico 8. Enemy hitboxes seem to be a bit taller than they should be, Mario bounces off of them earlier then expected, but other then that, the game feel is pretty much spot on. Good job!

P#141555 2024-02-16 11:34

Thank you, it's taken a lot of work. I have noticed the hit boxes are a bit off, I'll adjust those in the next revision.

Hey @JadeLombax, do you plan on releasing a version of this wonderful demake without compression? I'd love to toy around with it and see what I'd be able to make!

P#141579 2024-02-17 02:29

Hmm, that's a tricky one. I had to use a minifier to fit under the compressed size limit, partially because I'm storing all the music as strings, but even if I could squeeze it down enough without compression, the level data is all super-compressed as well, and requires a separate editor cart. Even then, I'm purposely avoiding releasing the full game so as to hopefully not run afoul of Nintendo's over-eager lawyers. I am planning to reskin the game and release that, and I could release a level editor along with it. I've also been thinking of releasing a streamlined version of the engine as a starting point for platformers.

P#141580 2024-02-17 03:31 ( Edited 2024-02-17 04:13)

Ah, thanks for the explanation, will definitely look foward to seeing the level editor and others.

Side note, Nintendo won't take your game down if the graphics and names are switched around, it worked with No Mario's Sky turning into DMCA's Sky!

P#141612 2024-02-18 01:36

Yeah, that's my plan, currently looking to base it on zep's Mimo & Jelpi characters & call it Pico Bros.

P#141614 2024-02-18 02:00 ( Edited 2024-02-18 03:05)

super marpio bros is a possible name

P#141616 2024-02-18 04:05

I like it!
