Hi!
I've been trying to figure out how to use PX9 to compress the spritesheets for my beat-em-up game, but I haven't been able to figure out how to use it properly.
I want to compress 2 spritesheets (and maybe the map as well) from the 0x8000 extended memory into the normal spritesheet/map, then decompress them back to the extended memory later.
Here's a look at the current sheets
If anyone could help, it would be greatly appreciated!
If you would like to see the details I've released so far about the game, you can look at my Twitter or its page on my website.

Made for Mini Jam 108. We started a day late and finished a day late. Standard PICO-8 controls. Z is select. X is back. Arrow keys move the selection.
It's can be hard for a lone hermit crab to survive in the wild. Luckily, this hermit has a giant sword! Chose between 9 action cards to defend yourself from predators!
Movement Cards (Green)
- Move - Move one tile in any direction
- Jump - Jump over a tile in any direction
- Charge - Charge in any direction until you hit something
Attack Cards (Red)
- Stab - Point your sword in any direction
- Thrust - Hit the tile in front of your sword, and return to your original position
- Spin - Hit all adjacent tiles
Utility Cards (Yellow)
- Idle - Stay stationary for a turn
- Swap - Swap positions with any enemy over land
- Rewind - Rewind your last played card
There are 50 levels, so don't feel like you have to beat all of them. The game also auto-saves, so you can continue where you left off.
Here's the itch.io link: https://alanxoc3.itch.io/stabby-crabby
alanxoc3 did the code (me).
greatcadet did the sfx/gfx (this guy: https://www.instagram.com/cadendrawsstuff/).
Simple turn-based battle experimenting with state machines. Any criticism is accepted. Not the best but at least I learned :D.
Description
The demo shows how your PICO-8 games could add dynamicity to sound effects depending on what happens and the action involving your sprites, depending on their position, speed etc... not just use a few prefab sfx or playing several different sounds to give the impression they react to the action (e.g. a vehicle acceleration, spaceship thrust).
Presets
There are 8 examples (presets, select them with 🅾️ and ❎) of sounds and each shows a simple preview of some game action. To interact with preset previews you basically change the Pitch with ⬆️ and ⬇️ keys.
The Note
At the top you see the two bytes representing the note, their address in memory (it's sfx 1), the values in binary (help you understand how 'components' such as Pitch, WaveForm, Volume, Effect are stored in the bytes) and their corresponding decimal values.
You can use ⬅️➡️ to select a different component and edit its value.
At the moment it's 'just a demo' (although it took me more than 2 weeks, longer than a single game dev) and it still doesn't offer some basic functions to copy into your game to implement dynamic sounds. I'll update it as soon as I test more myself on an actual game.
Hey bbs! I had a lot of fun making this city render for my fighting game. arrow keys to move and z and x to zoom in and out!
(The buildings are random gen btw)
thanks to freds72 for helping a ton with optimizing the thing!
So, I decided to try and make a thing where you can select 1 character and move that character, and then switch characters and start moving the other one, I got this idea from PolyMars, but I have one issue: How do I detect when 1 or 2 is pressed on the keyboard?
Code:
x1 = 64 y1 = 64 x2 = 64 y2 = 64 cur = 1 function _update() if (btn(0) and cur==1) x1-=1 if (btn(1) and cur==1) x1+=1 if (btn(2) and cur==1) y1-=1 if (btn(3) and cur==1) y1+=1 if (btn(0) and cur==2) x2-=1 if (btn(1) and cur==2) x2+=1 if (btn(2) and cur==2) y2-=1 if (btn(3) and cur==2) y2+=1 if (btnp(1)) cur=1 if (btnp(2)) cur=2 end function _draw() cls(0) spr(1,x1,y1,8,8,false,false) spr(2,x2,y2,8,8,false,false) end |
I was practicing extreme optimization and came up with this cart
There's not a lot to see here but what matters is that it works
Edit:The original took up 182 characters, this new version takes up only 176 characters
Edit2:Thanks to @p01, the new version takes up 133 characters. Unfortunately, not all the techniques
could be implemented without problems as racer 5 was the only one that could win in your code
Edit3:I was able to make the cart smaller by 3 characters which is not that bad
Description from the itch.io page:
You're a bee, and for some reason I still do not comprehend, you decided to get some honey. In the middle of the rain. The drops are twice as bigger than you. You might die if you get hit by one. And the rain gets worse the more honey you collect. That wasn't the best idea you've gotten.
Made in 4 hours for the Crunchy Jam, hosted by Celesmeh.
Still has noticeable bugs, since I couldn't get time for enough bugfixing sadly.

This is a utility for pico8, designed for editing map data. It will eventually be expanded upon, allowing you to edit and save to the pico8 extended memory. Its current major feature is allowing you to edit maps at 256x256 pixels, giving you a lot of breathing room.
I have chosen not to upload this to the bbs, for two reasons:
- It doesn't run properly on the web, due to the inability to pass commandline arguments to pico8 at startup.
- This is very much a "dev" tool, and not having it on your local PC doesn't make sense for its intended use case.
That being said, I encourage you to check it out, if for no other reason than to see how nice it is to have high-res utilities, and to see how easy it is to make them!
Setup
This cannot be run standalone - it must be run from the pico8 desktop client.
- Run this file from commandline, with the following arguments:
pico8 -displays_x 2 -displays_y 2 mapper.p8
- Code editing only takes place in the upper-left quadrant, which is why i edit the code externally in mapper.lua.
- Usage instructions:
Pan map around: ESDF Select a different sprite to place: Arrow Keys Switch between paint (point) and fill modes: B Save current map to cart ROM: 5 Export current map to another cart (you will need to edit line 187): 4 Paint or fill: Left mouse click Dropper: RIght mouse Click Undo: Z -- may be buggy!
Running in multi-display
If you are mostly interested in multi-display, this is my current understanding of it:
- You must run pico8 client from commandline, with the following args:
pico8 -displays_x X -displays_y Y -- X and Y are how wide and tall the displays will be, integers
- Within your cart, you must enable multidisplay with a poke:
poke(0x5f36,1)
- You now have access to four displays! you must switch between them manually, and draw to them separately. This is a major CPU consumer!
function _draw() for i=0,3,1 do _map_display(i) clr(i) circ(64,64,10,i+2) end end
Check out my mapping cart for tips on drawing across all displays seemlessly!
A small game made for the Lazy devs discord's game jam, the Crunchy jam!
The jams rules meant I had 4 hours to make the game, with those time constraints in mind I made this. You need to reach 100 to win- fall below 0 points and you lose!
little spaceship game i made. as per usual, started out simple, then had me bashing my head against the wall with frustration. but it turned out in the end.
explore the galaxy! follow the markers to find star clusters!
steer the ship with ⬅️ and ➡️! control your speed with ⬆️/🅾️ and ⬇️! hold ❎ to hyperjump to a new galaxy!
Z = possess/out
hold X = reset level

ive loved pico 8 the whole year, but now that schools over, i dont feel like playing as often. ill come in time to time, but i will probably not be playing at all anymore. i will never forget all of the amazing games created by all of you, but im afraid its my time to go. love you all, Jaeson Pickens.

Notes
- When all 11 levels has been completed, a special "zombie mode" is unlocked!
- Some of the levels are difficult, especially in zombie mode. We were tempted to tweak them in the days that followed, but decided not to, to honor the spirit of the game jam.
- We would love to hear your thoughts and comments if you played the game! ❤️
