How to use:

Arrow keys to move mouse
X to select. Will also open directory tree if not on a file
Z to close a file or return up a directory

Information on the project:

[hidden]This is my attempt at making a file explorer within Pico 8! It was made as a test to see if I could make something functional with minimal research prior or during. I spent about a month on this project, with the bulk of that in the last week or so after finals. Currently this program reads data from a table and takes the fields of each item on the list to determine how to handle the data. My goal for this point was to get most basic functions working and to have a decent user experience. Currently working are folders (return and directory), text files, and images. Images have an issue with lag depending on the "file", although that is when used at 2x scale or above.

I made this 'game' as a little thought experiment about the nature of Quantum Mechanics.

The idea here was to make a version of Conway's game of life that incorporates some 'quantum-esque' probabilistic behaviour.

Here is how the 'Game of quantum life' works:

The playing field is 64x64 cells and wraps around the edges both horizontally and vertically. Each cell can have one of 16 values, displayed as different colours. Cells that are alive have colour 15, cells that are dead have colour 0. Cells that are in superposition cycle through colours 1-14.

The seed is always created with a random number generator, according to the weighting you select on the start screen. The rules depend on the mode.

Classical rules (standard Conway game of life):

  • All cells can be alive or dead
  • Live cells stay alive if they have either two or three live neighbours, otherwise they die
  • Dead cells turn alive if they have exactly three live neighbours, otherwise they stay dead

Additional quantum rules:

  • Cells can also be in a superposition of alive and dead
  • Superposed cells with 2 or more live neighbours will be ‘measured’ and will turn either alive or dead, each with probability 1/2
  • Dead cells with exactly 2 live neighbours may turn alive with probability 1/8192.
  • Dead cells with less than 2 living neighbours may go into superposition with probability 1/4096.
  • Superposed cells with less than 2 living neighbours may turn dead or alive, each with probability 1/16384.

The “Copenhagen” and “Multiverse” modes both use the quantum ruleset, they only differ in whether a measurement is counted as a collapse or as a branching. The branch counter displays an estimate of how many branches were created in total from the seed, this is given as 2^

SantaMania

SantaMania is a rhythm based arcade game that started as a shmup and later turned into a boss rush. The goal is to finish the game with as much life as possible. All feedback is appreciated. Have fun!

The code runs on duct tape and wishful thinking, but if you have any questions about it, feel free to ask.

Special thanks to @Krystman for all the tutorials.

How to Play

Use the Left and Right arrow keys to control Santa.
Press X or O in rhythm to shoot "Ho Ho Ho."

Merry Christmas everyone! This winter, don't forget to spend quality time with your snowman friend. You can collect stars too if you like, but the real treasure is memories of whooshing through the snowy landscape together.

Use DPAD/cursors to fly around, and fly downwards for extra speed. After unlocking star mode, tab (or the pause menu) can be used to toggle it on -- press [O] (Z/C) to add a star and [x] to remove the last placed star. Toggle edit mode back off to return to collecting them.

Created for the 2024 PICO-8 Advent Calendar, which also comes as an itch collection. There are 25 great games in there, along with a lovely calendar cart by @SmellyFishstiks to explore them ~ check it out!

how do i test for big numbers that print different than their true value?

function _init()
 srand(39)
 a=rnd(-1) --prints -20954.2428
 b=-20954.2428
end

function draw()
 if b==a then
  ?"true"
 else
  ?"false"
 end  --prints false
end

I have some big numbers that would be nice to know their true value.
thanks and merry Christmas!

Abyssal Shooter is a simple shmup set within a deep underwater abyss. Survive 10 waves of vicious aquatic creatures by shooting bullets, launching missiles, and unleashing devastating special attacks!

This game was made by following Lazy Dev's Pico 8 Shmup tutorial. Big thanks to Krystman for an easy introduction to Pico 8 development.

Changelog:

v1.1 - Previous release started the player on a later wave w/ 2 bombs already built up. Reset both of these to zero as intended

v1 - Release!

Ho, ho ho! Merry Christmas 2024!

I made a little thing or whatever you want to call it, where you can decorate a little tree with ornaments, and a star.

This is one of my first projects on PICO-8, and my first Release on the BBS!

Intructions

In the very bottom left of the screen, there is a button that lights the tree on fire! Don't worry, it wont damage anything! And the button above that, adds snow!
But the button above THAT, resets the whole tree, smoke appears and then when the smoke fades away, BOOM, nothing on the tree.
Those three buttons use the amazing particle effects from https://www.lexaloffle.com/bbs/?tid=53826 by atzlochtlan, credit to them. *(I hope its not illegal to use without permission...)*

In the very top right corner of the screen there is a button to go into view/screenshot mode, #Merry will appear at the bottom, you can use the a-z, A-Z, 0-9, and Backspace keys, to change the text that appears after the hashtag.

If you move your mouse off the screen in view/screenshot mode, the button in the very top right corner will disappear for optimal screenshot/F7 taking conditions, and if you move your mouse back on screen, it will reappear, but I have found that in Web-View the mouse cannot properly move off the screen.

It's that time of year again — Christmas is just around the corner.
This is just a tiny demoscene-inspired greetings cart. Nothing special, just a bit of pixel art for our loved fantasy console.

Greeting to the whole pico-8 scene, appreciate it! Appreciate you, keeping the spirit alive.
To all coders out there and gamedevs, musicians and graphic wizards.
Big thanks to Lexaloffle.

Enjoy the holidays with your loved ones and families, and have a great start to the new year.

Overview
"Pen Factory” is a port of a mini-game that was originally included in Part-time Job Hell 2000 for Pico-8. The player, as a factory worker, is constantly putting caps on ballpoint pens that are flowing on the conveyor belt. There is no game over or time limit.

Game controls
Z key: Put a cap on a pen
X key: Rotate the pen to adjust the direction.

Rules
Check the orientation of ballpoint pens flowing on the conveyor belt.
Rotate the pen as necessary to attach the cap in the correct orientation.
If the cap is put on correctly, the score is counted. If you make a mistake, it counts as no score.
The game has no time limit or end condition, so you can continue until you are satisfied.

At this time, there are no plans to release the source code. Sorry!

Just curious, what is the "Profile Header" in the profile settings?
I was thinking it might be like a signature that pops up at the bottom of each message?
But i'm not sure..

I set it to "test" to see if anything would happen.
