Hello all, this is My First PICO-8 Game™ï¸Ž and therefore My First BBS Cart Upload™ï¸Ž™ï¸Ž, hopefully I've done it right.


Unchecked-8 is a slight twist on the classic spike-jumping, maze exploration platformer. There are simply 10 stars to collect. Once you figure out how it works, I estimate it takes 15-30 minutes?
I wanted to dive into PICO-8, make something reasonably small, and actually release it - so I chose a remake/demake of my own short game Unchecked (previously existed in Flash and Basic). I like this so much it's now the canonical version of this game!
I first put it up on itch.io, because it had some HTML player customizations and also to hide My First P8/Lua Code™ï¸Ž™ï¸Ž™ï¸Ž










A game about shooting aliens that i made cause boredom.
The collision system is also trash but i can't make it better

Anyways, it's pretty cool and i have like 3 days working on it, so please tell me what you think in the comments too!
and also print("have a good day :D")


Hello all...
Two things I want to ask about but don't think it'd justify two separate threads.
1/ Can someone explain how to do a particle explosion thing that emits in a circular pattern?
I've experimented with particles for dust etc. but thought it might be nice to have a pickup emit a circular particle system when picked up. I don't know how to work with the x and y for each particle.
2/ Can someone point me to a tutorial or code, or whatever for those old school passcode systems for level/life/score saves. I wanted to have a system in their as a homage to games gone by that one would type in a 5 digit passcode and it would carry on the game where you left off. Like Bubble Bobble used to have.
Thanks for your time.

Pay attention to the top row, where the digits 0123456789 have been shuffled. Move the cursor right and left to choose a digit; press a button to select the digit. Your goal is to select four digits which are in order, or in reverse order. (Keeping a consistent beat to your inputs will cost you less life.)
If the presented digits were 5709134682, you could win by clicking on 0, then 1, then 3, and finally 4 since those are four increasing digits appearing in that order within 5709134682. At that point, you will be presented with another puzzle. You can also win by choosing four digits in reverse order.
The visualization in the center makes it easier to find these patterns.
That this is always possible is a consequence of


Like the 99 bomb Spelunky Deathmatch I used to play, for 1 or 2 players.
This is my first real Pico-8 project (after a failed attempt at Pinball). I'm happy with how it's turned out. The AI isn't perfect, but can provide a really decent challenge. It may be improved in the future.
O is bomb, Down is pick up, O while holding is shoot, X is jump.

PICO-8 0.2.3 is now up on lexaloffle, Humble, itch.io, and for PocketCHIP.
This update is focused on resolving runtime issues, with a couple of small but handy features thrown in for good measure:
Lucky Draw
To grab 32 random cartridges from the BBS, there is now a 'Lucky Draw' list in SPLORE. It is more likely to select cartridges that have more stars, but even unrated carts have a decent chance of appearing. Perhaps this will be a way to unearth some undiscovered gems, or just to find something new to play without scrolling back through several years of carts.

The list is cached, so it only changes every 2 minutes or so. But you can keep paging through the list to get new items forever.
Live Token / Character Count
Select some text in the code editor to view how many characters or tokens are contained within.










A simulation of the famous Monty Hall Problem inspired by the game show "The Price is Right."
The game goes like this:
0) 3 doors, 1 has a pile of gold coins behind it
1) You pick 1 of the 3 doors
2) Monty Hall, the show's host, opens 1 of the 2 remaining doors, revealing that it is empty
3) You are offered the chance to switch to the remaining closed door
4) All 3 doors are opened and you receive what's behind the door you ended on
The Problem:
What is the probability of winning if you switch?
What is the probability of winning if you stay?
Is it always better to switch or stay? A little of both?
Does it matter whether you switch or stay?



Hey guys,
There's an Alakajam! event scheduled for the 17-19th September week-end!
If you don't know about us, we're an online gamedev community hosting jams, where you are invited to make a game from scratch over 48 hours. Start/end times are suited to European timezones (7pm UTC), while both the theme and the winners are decided by the community! As I write the theme submission phase has just started, and you will be able to suggest ideas for one week. The full jam works this way:
You can discover the winners from the last jams here</a>. PICO-8 has been a popular engine throughout the events, some of them even winning the solo category :)
More than the thrill of the competition, a cool thing is that all games are getting valuable feedback for their games thanks to our voting/comment system.
I was working on a new project that involved learning how rom cartridges worked, so I asked around for help and someone suggested that I use SD cards. I ended up liking the idea and decided to use that in my current Pico 8 fanmade handheld project as well. What I did was created a shell that goes around a SD card to give it a cartridge look and feel. A USB SD card reader will read the 'cartridges'. I also wrote a bash script that will search for a p8.png file in your SD card directory and have Pico 8 run that file or run splore instead if no SD card cartridge was connected. Firstly, when you plug in a SD card to your card reader, you should type in
sudo fdisk -l |
. This should list your SD card. Mine was listed as /dev/sda1
I then mounted the SD card and made sure Pico 8 could run the file. While in my Pico 8 directory, I typed in
./pico8 -run /media/usb0/run.p8.png |
and Pico 8 ran the file, but use whatever directory you mount your SD card in. Why did I call the cartridge run.p8.png? I tried just using
./pico8 -run /media/usb0/*p8.png |
, but I thought, if I had multiple cartridges on the same SD card, it would pick one out of random, and I didn't want that, especially for multicart games. Maybe there is a better way at doing this. If there is, please let me know. I made it where the first cartridge can be called run.p8.png, but other cartridges can be called whatever you want. I modified /etc/rc.local and added a line before the screen driver where it would mount the SD card. For me, I put in
sudo mount /dev/sda1 /media/usb0 |
I then created a bash script that would either load a game from a SD card cartridge or run splore if there was no cartridge connected.

@zep
This problem has happened to me multiple times now where I'm doing music in the sfx editor, (and the pattern editor maybe?)
And I hit cmd+r.
Pico-8 crashes immediately and I've checked my backups folder to find this time nothing was saved...
I'm not sure if it's because I don't have any code and I just made a cart to do music in, and it doesn't happen all of the time when you run, but when it does happen it crashes and you lose everything :(
I'm not sure how to recreate it but if you could find it please squash this bug/crash, thanks.
I'm on mac, version 0.1.12c
