This is a little demo I've been toying with. Its really barely a game, but it does show off a couple useful functions:

  • Generated ground tiles with some decorations.
  • Collision detection between the player character and the generated ground.
  • Drawing triangles.
  • Rope physics effects, used for the characters tail and flags.
  • Some simple decorations, like clouds and background mountains.

There's really no "Game" in the sense that there's no objective or fail condition (although if you fall off the screen you're probably in a non-recoverable scenario).

To take root Among the Stars is a short narrative platformer.

Play as Mei Hashimoto, one of the colonists send to an exoplanet to prepare it for the arrival of the rest of humanity.

Explore the colony and its surrounding flora and fauna. Talk to your fellow colonists and send a message to earth via the relay station at the top of the nearby mountain.





To take root Among the Stars was developed by Simon Klein.

While they made a variety of different games in the past, this is their first foray into a narrative focused game.

It was developed in the span of about one and a half months using Pico-8, a virtual Fantasy Console by Lexaloffle.

Thanks to the folks on the Pico-8 discord for help fitting the whole game into the limited space, and @Gruber_Music for their excellent introductory music tutorials.

Github repo here -> https://github.com/lesleyrs/pico-paint

This is my first completed cartridge, made for people who don't like clicking or want to try something new.

It allows you to paint, copy, and paste 8x8 pixel art into pico-8 games without requiring a mouse.

Key shortcuts:

  • arrow keys to move
  • x to paint
  • c + up or down to change active colour
  • c + left to turn background colour into active colour
  • c + right to change move delay
  • enter for the other settings

Copying and pasting is not as efficient as i'd like because of the built-in limitations of writing to and reading from clipboard. Make sure to ctrl-c after pressing copy in menu, and ctrl-v before you press paste in menu. try:
without extra characters or it won't load.

Voronoi-adjacent thing. Can't quite fill a screen with these, but it's still a neat effect.

This is a re-skin of Pac-Man [#TinyTvJam] made by Scathe in 2017. I wasn't able to put the logo of my game, so there is a silver Pac-Man logo at the back of the arcade cabinet instead. Hope you joy this game and feel free to leave some of your thoughts

Is there a way to know if a channel is busy? I think it is not in the manual, but perhaps I've miss something.

I think ever since @carlc27843's Impossible Mission R.T. cart came out, people have been wondering if they could make background music for a cart using PCM synthesis. carlc27843's Emulated Amstrad CPC Chiptunes post discusses using its engine that way, @luchak has had to let people know that the RP-8 groovebox can't be used that way ... folks are curious.

I don't know a lot about digital audio synthesis, but from the conversations that have happened in the PICO-8 Discord, it sounds like there's roughly three sides to the equation:


  • How many tokens and bytes are cart designers willing to give up to the soundtrack? @bikibird's Speako8 Speech Synthesis Library is under a thousand tokens - is that a good target?
  • What percentage of PICO-8's CPU budget? Four voices with 25% CPU seems possible in a few different ways, but is that too much to give up to background music?
  • How much memory, Lua and addressable? Most forms of synthesis probably run out of CPU first, but this could be a question if you're making a lot of lookup tables.


  • How do you program tracks? Does it use PICO-8's built-in tracker with its own sound sources? Does it have a custom editor?
  • How do you add them to your games? Presumably you copy a bunch of code into memory and add a function or coroutine to your game loop, but where and how do you store tracks?


  • How many simultaneous voices? PICO-8's built-in tracker allows 4 simultaneous sounds, but most game BGM is built with 2 or 3.
  • What effects can you add? Reverb is probably out of budget, but echo is possible (if memory-expensive), and distortion and compression are totally feasible. As are filters - certainly low pass, high pass, band pass, and notch.
  • What kind of synth do you make?

It's definitely possible to make:

  • Simple waveform synthesis (e.g. sine, square/pulse, sawtooth, triangle)
  • FM synthesis
  • Sample-based synthesis (very storage-expensive!)
  • Wavetable synthesis (the original PPG Wave synthesizers only had 8-bit samples! but this is also storage-expensive, if less than sample-based synthesis)
  • Subtractive synthesis with any of the above as oscillators

...but the more processing you do, the more sound design tools you add, the more expensive your result will be.


I don't really have one? But I think it would be good to have a space on the official forums where people who are thinking about this stuff can talk about it. I haven't made a lot of games, so I don't know what what a good budget would be for game developers ... and I haven't made much music with much outside PICO-8 and, like, an actual piano, so I don't know what a good synthesizer would be for game soundtrack composers. And I know barely anything about software synthesis, so I don't know what's possible, what's easy, what's hard, or why my low-pass filter makes hell noises if I give it the wrong parameters.

I think it would be cool to share knowledge, and the forums seems like the best place to do it.

Goats, Cars n' Doors!

Cart #goats_cars_doors-1 | 2023-01-18 | Code ▽ | Embed ▽ | License: CC4-BY-NC-SA


the situation being proposed is: there are 3 doors, behind 2 of them are goats the other has a new car. you (trying to get the car) pick a door, the host stops you and opens a different door. behind that door is a goat. they then ask you "do you switch your answer".

the question: what are the odds of getting that car if you switch vs. not switching.

the problem: everyone i've asked has said its a 50% chance either way, but the answer is actually 2/3 if you switch. why? I have no idea but I built a simulation so you can answer that yourself!
