I have a cart used as an ongoing reminder alarm, simply showing the previous alarm, the current time, and the next alarm. It runs continuously for very long periods, e.g. weeks. Indeed, this instance has been running since the week 0.2.0i came out.
Today, for the first time I've ever noticed, the display was showing a pattern of corruption. I took a screenshot, but there was no corruption in the screenshot, so I tried saving a gif. I have my gif len set to a couple of minutes, so the result is quite long.
If you pay attention, the gif shows the parts of the pattern changing every second or three:
And yet when I saved a screenshot at the same time, there was no evidence of the corruption:
I assume this is because the PNG is saved from a point in the pipeline that comes before the corruption, while the GIF is saved after the corruption.
This means the cart itself isn't producing the corruption. It's happening somewhere in the frame presentation pipeline.

Guide your ship and pick up each of the boxes and bring them back to base, while defending yourself. Can you make it through all the levels?
Inspired by the amazing game published by Kingsoft in 1989 on the Amiga with the same name.

Hi
Short question this time. What is the least-bloated way to insert a value into a list at the first index using add(). I couldnt figure out a method which is elegant and simple.
Thanks

Hi
I am making a roguelike and i would like to add in procedural generation of rooms. I would have prebuilt rooms in the map editor and when the character goes below, above, left or right of the current room, it would take them to a new room with which that entry was possible. I can do this ok apart from one thing:
How do i store the layout of the rooms once you go into a new room? If it was just left and right i would make a list of the coordinates of the rooms and when the player goes to the right, a new random room would be appended at the end, if it is to the left then at the beginning. Though this doesn't work when i have up and down too. How do i store the coordinates of the rooms that the player has already been in is my question.
I would appreciate some help
Thanks

This is a mod made by me and Taco360. I did most of the level design and made the dialogue, Taco made all the extra sprites and code changes, as well as designing a few of the levels. EDIT: A lot of people have had trouble with this and I didn't make it super clear, but if you want to do a normal playthrough follow the arrow in 900 that points right unless you want to do gemskip. Sorry about any inconvenience this may have caused, and hopefully this doesn't ruin the mod for anybody.

PicoPlex
by lunafromthemoon
Hello everyone, this is a remake from an old game called Supaplex, that was itself a remake of an even older game called Boulder Dash. It was my favourite game as a kid. This is my first game in Pico8 and it was hard, but a lot of fun. The music was done by my dear friend lisergishnu, and I also had some help to pack the levels from thisismypassword.
Hope you enjoy!
And please, let me know if you find any bugs.
How to play:
The game is very simple, you are Murphy, a little red ball, running inside a complex computer system. Your goal in each level is to gather infotrons (the colorful thingies) and get to the end. But be careful, there are many dangers ahead, like falling zonks, snik snaks and bugs!
Check the cast page by pressing X in the menu!
In the main menu you can choose a level (there are 111!) and start by pressing Z. You can play any level you want, no need to go from 1 to 111. When you win a level, it will be marked in green. Can you win them all???

Hi, I'm confused about the following. In my platformer game I apply a 0.85 factor to dx as friction. When I do this on a negative dx value (i.e. player moving to the left) dx never reaches zero and is represented as -0 (minus zero).
When I use that dx value by adding it to x, the x value keeps counting down a tiny fraction on every update.
I can work around it of course (e.g. setting it to 0 when abs(dx) is smaller than 0.0002), but I'd love to understand what's actually happening here. All pointers are appreciated :)
You can see it in action here:

Harvard University's CS50 Games course has a free online version on edX. It's a great class for beginners with some coding experience, and uses Love2D and Lua. Nearly all of the concepts apply to PICO-8 development.
https://courses.edx.org/courses/course-v1:HarvardX+CS50G+Games/course/
It's not too difficult to translate in-class code to PICO-8 equivalent code, but it might be easier to stick with Love2D for the course, then figure out PICO-8 equivalents later. In-class code uses Lua standard library features, all with PICO-8 equivalents. Spreading code across multiple files could be done with code tabs or "#include" instead of "require". They also use a simple third-party object-oriented class package to teach OO concepts. This could be ported to PICO-8 but hasn't been yet.
If there's interest, I'm sure we could pull together a set of support materials for bridging CS50 and PICO-8. For now I'm just recommending the course.

Hello!
I am making a new metroidvania and i feel like a critical part of this is getting the jumping to feel right. I tinkered with it for a while before i realised that a true metroidvania really needs variable jumping, where the longer the button is pressed the higher you go. I have had some issues with implementing this and i would appreciate some help.
Thanks!

Hi there,
This is the prototype of my remake of ANTS (http://www.homeoftheunderdogs.net/game.php?id=3761) which is a remake of Arcomage. This version is already fully playable.
You take turns playing cards against the computer. You goal is to build you castle (the left one) up to a height of 100 or destroy the computer's castle (the right one).
This version is not 100% ANTS, I had to reduce the card hand size from 8 to 7 (notice that Arcomage has only 6), but all cards are included (I renamed some and I tweaked some minor stats).
Features still missing:
- sound effects
- music
- some gfx could be nicer
- difficulty settings
Tell me what you think of it and what I might improve.

Ramps
This is Ramps! A 3D racer inspired by Powerdrift, Stunt Car Racer, Hard Drivin'.
Choose from 8 varied race tracks, and overtake the other drivers in 5 laps to win.
As well as racing you'll need to navigate jumps, roller-coaster like ramps and occasionally even drive upside down.
Includes 3 difficulty levels, plus a practice mode for getting the feel of the tracks.
This all started as an experiment to see how well Pico-8 could render a Powerdrift-like scaled sprite racetrack (pretty well, as it turns out). Then it was about trying to implement a driving model that could handle the ramps, jumps and loops. And finally wrapping it up into a somewhat finished game.

:: Changelog v2::
- Fixed typo preventing fizzles from spawning
- Added more animations
- Changed some text to be clear
- Still missing : proper game over screen, effects of combining elements
:: Changelog v1.1::
- Fixed screen transitions
- Added some more animations
- Fizzles now spawn continuously until you open the exit portal to prevent getting stuck
You are Mozle, a tiny astronaut who crashed on a mysterious world with mirrors and neverending roads !
Gather Fizzles and combine Elements to power your ship (and get points) and get back home !
Go through the different portals to catch Fizzles and collect their energy bubbles to open exit portals, collect elements top open the exit, collect time and points ! Hurry, because time is unstable in this world !
Press O (x on your keyboard) to jump !
Press X (c on your keyboard )and down to fall through platforms !
Press up in front of the spaceship to combine elements you found !
The code is pretty messy, it's missing a proper ending and some features I couldn't cram in (end boss battle, cutscene intro, gameover screen), but I hope you'll find it enjoyable.
PS: if someone with proper musical skills could help me it would be greatly appreciated !

I made a (very simplified) clone of the mobile app Daddy Long Legs. Here is that!
v2 (shows high score on the ground to better show if you have passed your highscore)
v3 (sound)
