So this had bugged me for a long while for binary versions of games, how to load in data while the game was running using the serial connection. I had a quick look for examples but couldn't find any, so if anyone else is struggling with how to do it then this code might be useful for you.
To test it down download the code and run it. You should be able to press X to generate some data to your clipboard (or swap code add in printh command). Save that as a text file. When running just drop the file in and you'll be able to see the data being loaded into memory.
You can tweak a few variables to load in anywhere from 0xf to 0xffff.fffff values which you can then post process to have loaded data for your game.
Hopefully this is of some use to someone struggling out there. For me, I'm going to use it for DLC content
NOTE: This doesn't work with BBS games, and when using HTML versions would would need to mess about with the template load it it in that way. This is just purely for binaries or when developing.

I'm pretty sure I remember this working correctly in a previous version but as of version 0.2.5g if you navigate left/right through patterns in the music editor using the -/= keys on the keyboard, if you get to an empty pattern, the keys no longer work and I haven't been able to find any way to regain control of moving through patterns except by using the mouse.

So, I thought I'd give it a shot. Never made any real game on pico8. I simply described what I wanted and asked for clarifications and added features. This was done using ChatGPT 3.5 in about 2 hours. (Could have been much faster. Even the first prompt generated an almost playable though yanky game after fixing a slight error.)
The first prompt was: "In pico-8 implement a side scrolling shooter using gamepad controls. The player spaceship is represented by the string "World world" in white color. It can only move up or down. It is firing shots represented by the character "-". Enemy ships are entering the screen every 3 seconds at random speed and random y coordinates from the right side. They are represented by strings of words randomly drawn from a list containing "wtf", "ftw" and "GPT". They are colored red. Enemy ships are destroyed when touching the shots from the player. The player is destroyed when he touches an enemy ship. Upon destruction, an enemy ship flashes 3 times in white over the course of half a second and then disappears. Upon destruction of the player spaceship, it is moved to the left, off the screen. One second later, it reappears on the left side of the screen. Display two counters at the top of the screen named "Killed" and "Kills". The "Killed" counter increases each time the player ship is destroyed. The "Kills" counter increases each time an enemy ship is destroyed."

Ludum Dare 52 - Delivery
https://ldjam.com/events/ludum-dare/53
Bundle Dumper: Florida Edition
Hurl babies through five exciting levels (including a tutorial level) in this flappy inspired side scroller with a Floridian twist! Also my first complete PICO-8 game, so now you've been warned.
Controls
It's a PICO-8 game, you get what you get and you don't get much:
- left and right arrows to change direction
Zis the circle button (Con keyboards that nobody uses in Florida)Xis the cross button (Von keyboards that nobody uses in Florida)- But save yourself the wrist strain and just use a gamepad/controller!!!
Mechanics
- Flapping increases vertical AND horizontal momentum (that is, flapping while turning changes your direction faster)

I've been enjoying playing around with Pico-8 recently, and decided to use it to enter Ludum Dare 53. The theme was Delivery, so I made a ChuChu Rocket inspired arcade puzzler sim thing - place arrows to direct the lorries to make deliveries.

I didn't realise until way too late that I'd need to make a cartridge label image and cover image, so sorry if it looks a bit garish!

basic shmup, but shooting spawns more enemies
This is the first playable result of following the basic shmup tutorial by Lazydevs.
It is not fully finished yet, but it is at a point where it's reasonably fun to play around with.
Shooting spawns more enemies, this was origingally a placehoder to test enemy collisions, but I think I will keep it like this in the game.
I might end up making a normal version too at some point.
future improvements
- The game over screen could use some love.
- Enemies don't shoot yet, they should.
- I will probably add a pickup, like a muffler, that allaws you to temporarely shoot enemies without spawning new ones.
- It needs a better scoring system.

Here's an orange and some sandwiches for The Wizard. Use the dpad (or cursors) to control the owl, and watch out for castle creatures. Also, take care of the basket ~~ if it hits a wall too hard, it might smash. Good luck!
This is a short game made for Ludum Dare vol.53

Here is a version of Asteroids for Pico 8.
This was made by following the Bytes and Bits tutorial on Youtube for making an Asteroids clone using the Tic 80 console.
It's a great and very educational tutorial. I highly recommend it.

I tried to recreate the look and feel of the original arcade version.

The following code block prints only the number 4, though I would expect it to print 2, 3, and 4.
do if (false) if (true) print(1) print(2) print(3) end print(4) |
Only the outer if has this property, the inner if's scoping is fine. Similar behavior happens without the do block, I just included it to demonstrate the interaction of this behavior with "normal" Lua scopes.

This cart uses devkit mode so you'll need a mouse and keyboard to use it.
Update:
This started off as a level editor for the Space Taxi Remake I'm working on. At some point I realized I was going a bit overboard and instead of doing the sensible thing and saying, "well that's good enough for my purposes I guess I'll stop now," I just kinda leaned into it.

I recently discovered that the education edition actually works really well on my phone using my Bluetooth keyboard, but carts being erased as soon as the browser refreshes or the phone locks etc just isn't practical lol. I think Pico-8's artstyle really suits the smaller screen and it's a shame there doesn't seem to be an app of the full version. Anyone else try this out or have better suggestions? Thoughts?

Bury a dancing crow behind a wall of peanuts. This is what it wants.
Hey! This is an idle game designed to put the player in tension between queuing more actions (and hence making progress) and actually witnessing the gameplay.
Also, there's a chiptune. It incorporates Pico-8's built-in sound, but also some homemade synth code for the bassline.
Epilepsy warning: there's a little flashing, but all of it is localized to small areas of the screen. (under 16x16)

Well, I've always been a big fan of FPSes, so I wanted to try to see if I could pull off making a raycaster. So, I made a top-down maze-style "game", then focussed on getting the raycasting to work. It's based off of what Isaac Games has done with raycasting, and I've also got a "shoot" function, though it only works once (so far).
That being said, unlike my earlier releases, this isn't really a game, more of a "baseline" that I might use to make raycast FPSes in the future. I still need to work on stuff like textured walls, doors, enemies,, some fine-tuning, "smooth" walls, and maybe even actual levels. That's a ways off, so I hope you enjoy what I've managed to do so far!
