A simple way to break Pico-8's palette.
Changing the screen palette using poke(0x5f2e, 1)
and then changing the red or dark red / purple colours, then running, exiting, and going to the sprite tab results in the above image. The red and dark red colours get pal
ed in by Pico-8.
Thought it would be an interesting first topic. Have a good day!
i'm prepared for explanations that may contain math.
i have been working on this for too long over many attempts. it kinda works but there are definitely still issues.
i'm having problems with...
- normal calculations being off only some of the time
- when a shape returns to it's normal size, another the shape it collided with previously will get stuck inside
- shapes hovering 1 pixel over the ground???
- shapes are very bouncy
- shapes will not stay on other shapes (line segments can't collide with singular points)
- jiggle (i'll implement damping later on.)
- and cpu (not a priority yet, AABB tree later)
there are some comments that will hopefully help you find the issues in constrain()
and shape_collision()
im tryin to make a platformer base to use for future projects, but when travelling in positive directions, the collision is seemingly not detected until a full pixel further than it should be

Hi all,
I decided to create my own take on the PICO-8 Cheet Sheet. 👨💻🖼️
Inspired by @LightBWK's version - I wanted to try to make a 4K one using a clean, modern look.
Light Version
It was also important to me to have a matching "Dark Mode" variant, as that's my go-to style 🕶️
Dark Version
Main Features
- 🖥️ 4K (3840x2160) Resolution
- 🔠 Clear, Monospaced JetBrains Mono Font
- 🔷 PICO-8 API up to v0.2.5g
- 🎨 Full PICO-8 Palette (inc. "Secret" cols)
- 🦓 Matching "Light" and "Dark" variants
- ⌨️ All Major PICO-8 Keyboard Shortcuts
- 🖌 FILLP() Mask + Glyph Patterns
- 🔄 Turn-Based Angle + Trigonometry Primer
- 🈂️ Full Character Set

Picoblazer 1K: A #pico-8 homage to the epic 1986 Trailblazer for Commodore 64, in 1017 bytes of compressed lua code. Produced for the 2023 #pico1k jam.
Use the left and arrow keys to direct the ball to the end of the track, while avoiding pits. Red tiles will bounce the ball back while green ones will speed it up. Blue tiles will cause it to leap forward.
I recently finished a game for the Cre8 Jam. You control a robot through commands to move through and scan a 3d environment. I would have added a bit more or fixed it up better, but I'm about out of time for the jam and really low on tokens. Even after using special functions to lower the token count.
You can get more information through the HELP
command, but the main commands are:
MOVE (direction) (amount) TURN (left/right) (amount) WAVE SWITCH [name] SCAN (dot size) |
And another important one is RSCAN
, which is just SCAN
, but repeatedly scans.
I would highly recommend checking out the itch.io page, as its design is special for this game.
One button tiny physic-based platformer made in Pico 8 with code under 1024 compressed bytes, made for #Pico1k jam 2023
Use RIGHT ARROW to accelerate when on the ground
Release RIGHT ARROW to fall faster when in the air
Press UP ARROW to start a new level
Press ENTER and select SEED in the menu to start from level 1 if you want a fixed series of levels
Number on top left is a timer for your run of the level, counted in frames (at 60fps), on top right is the sum for all the levels in your session. For example a casual run of all the seeded levels from 1 to 10 took me 14027 frames. My PB for level 1 is 1071.
Source as p8 are available on https://nusan.itch.io/smooth-ride in two versions, the "comment" version is what I coded with additional comments, so it's readable but the "minimal" version uses a tool (https://thisismypassport.github.io/shrinko8/) to makes it even tinier, it's not readable but it fits into the 1k compressed bytes target
