Howdy, new to Pico-8 and I am making my 1st game now.
I seem to have some off issues with the SFX and getting certain sounds to play.
I will make a video to explain this more if what I am about to type does not work.
I want a "Sonar" sound to play while the person plays the game. I made a simple blip sound affect and at the beginning of my main _Update() I used SFX(10) as that is where I made the simple quick sound.
It won't play.
I can instead make a screeching noise, explosion, that plays fine the whole game but who wants that. haha.
So, while one sound, same SFX(10) plays the second I start polaying, if I alter that same SFX(10) to age more bass low pitch blip, nothing.
I find that odd.
I can play the noise in the editor fine by hitting space bar.
In the game no luck.
Do certain sounds just not play? Do I need to move this to some music() instead, which I am more clueless on right now now.
But, I want a constant low bass blip like a sonar during gameplay.
A short game inspired by the Stephen King short story Trucks, made during November for PiCoSteveMo 3.

MORPH - A tactical 2-player battle game
Two warriors face off in a hellish arena. Move strategically, attack your opponent, and harness the power of blunders to morph into stronger forms!
Made by Marshy & Mike
HOW TO PLAY:
• 2 players take turns planning 3 actions each round
• Actions resolve simultaneously
CONTROLS (Planning Phase):
• Vertical arrow keys / vertical d-pad: Move UP/DOWN
• Arrow / d-pad toward your enemy: Attack
• Arrow / d-pad away from your enemy: Blunder (intentional mistake for power!)
• O button: Confirm plan
• X button: Clear/redo plan
GAMEPLAY:
• Hit your opponent to gain morph power
muOS screenshots
I'm currently using muOS on my RG CubeXX.
On muOS version 2508.3 (Golden Goose) the shortcut for screenshots is L2 + R2 + X. Screenshots are saved as 720x720 PNGs in the MUOS/screenshot folder.
This works in native PICO-8. The handheld rumbles to confirm a screenshot was taken.
Sometimes, though, I want to take a screenshot without triggering the ❎ button...
CTRL-6 screenshots
I edited MUOS/save/pico8/config.txt and added 29=224,27=35, at the end of the map_scancodes line.
This maps L1 and R1 (the only buttons that trigger key scancodes) to LCTRL and 6, respectively.
Desktop path
I also had to add /mnt/sdcard/MUOS/screenshot/ at the end of the desktop_path line in config.txt so that CTRL-6 screenshots are saved on the screenshot folder.
Note: use mmc instead of sdcard if you want your screenshots to be saved in SD1.
It works!
Terminal Front
Terminal Front is a bullet hell type game made to look like a terminal, with your actions taking up precious screen space. Navigate across a sea of swarming characters, reaching for that ever growing score; careful, difficulty increases the more you play...

Hey all, this is an entry for the 20 second game jam 2025 made by me and my family.
You are a Werewolf who wakes up locked in a mansion and needs to escape! You have 20 seconds till everything is locked down.
Use shadows to your advantage, the guards cannot see you when you are shrouded in darkness.
Collect keys to unlock doors to make your way out of the mansion. You can boost to get away from the guards if they spot you.


This upload is mainly to test cartridge export fucntion :)
Current state of the game:
- Procedurally generated 100x100 tiles map
- Generated different types of terrain based of "walls" blob size
- Basic movement and collision detection
Just restart the cartridge to get the new map.
Stay tuned for more updates :)
UPD v.0.1.5
Optimize map generation code. 3x faster, 3x less readable :)

I'm curious if what I wrote can be done a lot more simpler. And I'm trying to figure out how to improve it. The issue is, because of the order in which the game checks for input, if I hold down right and then press left the character moves left. But if I hold down left and then press right the character keeps moving left. (same for up and down.)
Since I was trying to make a stupid simple monster catching clone I booted up pokemon emerald to check how that game handles input priority. And funny enough it doesn't, it has the same issue as my movement does.

PICO-TRIO — A Pocket-Sized Otrio-Inspired Strategy Game!

HANGAKU GOZEN: one hundred arrows
Become the famous Japanese female archer and carry death with each arrow you release into the air. Collect arrows shot by your enemies, dodge spears and shurikens, and figure out how to deal with 5 different enemy types. Be quick, but patient, and earn the TRUE HANGAKU stamp.
In 1201 Japan, Hangaku Itazaki from the Taira clan joined her uncle, Jo Nagamochi, in his Rebellion aimed to overthrow the Kamakura Shogunate. During three-month long defense of Torisaka castle, Hangaku commanded 3000 soldiers to defend against 10 000 soldiers loyal to the Hōjō clan. Dressed as a boy, Hangaku stood on the tower of the castle, and all enemies that approached her were shot down by her arrows. According to historical records, for each hundred arrows she shot, one hundred enemies dropped dead.
