Happy holidays! Png2Gfx can take a folder of PNG files and automatically import them to a new GFX file! Please keep in mind it's expected that the PNG images are already using the default Picotron palette. See the gif below for an example!
My recommended workflow is to create your sprites in Aseprite, and when it's time to export, export all frames as png to produce individual images from the frames! Then place them in your Picotron drive somewhere, fire up png2gfx, fill in the source path, output path, and name, and hit Go! The app will create the full path if it doesn't exist, as well.

CHANGELOG

26/12/2024

-Added index 32 to palette map to allow for importing sprites that use #202020 for opaque blacks just as Picotron's default palette uses in-app.

f64 userdatas have the following arithmetic operations:
add, sub, mul, div, mod, min, max, idiv
We can create a few additional useful operations using just these.

local function ud_floor(x) return x-x:mod(1) end
local function ud_floor(x) return x:idiv(1) end -- Alternative. Faster for userdatas smaller than ~270 elements.
local function ud_round(x)
  x += 0.5
  return x-x:mod(1)
end
local function ud_ceil(x) return (0-x):mod(1)-x end
local function ud_abs(x) return x:max(0-x) end
local function ud_sign(x) return x/(x:max(0-x)) end -- Not zero-safe.
local function ud_positive(x) return x:max(0)/x end -- Not zero-safe.
local function ud_negative(x) return x:min(0)/x end -- Not zero-safe.
local function ud_tern(c,a,b) return a*c+b*(1-c) end

Here are some other useful userdata math tricks:

local function sum(x)
  return vec(0):add(x,true,0,0,1,1,0,#x)[0]
end
local function prod(x)
  return vec(1):mul(x,true,0,0,1,1,0,#x)

Abyssal Shooter is a simple shmup set within a deep underwater abyss. Survive 10 waves of vicious aquatic creatures by shooting bullets, launching missiles, and unleashing devastating special attacks!

This game was made by following Lazy Dev's Pico 8 Shmup tutorial. Big thanks to Krystman for an easy introduction to Pico 8 development.

Changelog:

v1.1 - Previous release started the player on a later wave w/ 2 bombs already built up. Reset both of these to zero as intended

v1 - Release!

Ho, ho ho! Merry Christmas 2024!

I made a little thing or whatever you want to call it, where you can decorate a little tree with ornaments, and a star.

This is one of my first projects on PICO-8, and my first Release on the BBS!

Intructions

In the very bottom left of the screen, there is a button that lights the tree on fire! Don't worry, it wont damage anything! And the button above that, adds snow!
But the button above THAT, resets the whole tree, smoke appears and then when the smoke fades away, BOOM, nothing on the tree.
Those three buttons use the amazing particle effects from https://www.lexaloffle.com/bbs/?tid=53826 by atzlochtlan, credit to them. *(I hope its not illegal to use without permission...)*

In the very top right corner of the screen there is a button to go into view/screenshot mode, #Merry will appear at the bottom, you can use the a-z, A-Z, 0-9, and Backspace keys, to change the text that appears after the hashtag.

If you move your mouse off the screen in view/screenshot mode, the button in the very top right corner will disappear for optimal screenshot/F7 taking conditions, and if you move your mouse back on screen, it will reappear, but I have found that in Web-View the mouse cannot properly move off the screen.

A simple terrain generation algorithm using the midpoint displacement method.

Hi! Been starting my coding journey on Picotron and I found that while writing on my spanish keyboard, every time I accidentally pressed my ñ, ´ or even ¿ key I get garbage sent to my screen... maybe that can get checked out? it writes two weird placeholder(?) characters on any text input I was currently writing, and it leaves the cursor between those two after writing it.

On this image, I wrote "qwertyuiop´+ asdfghjklñ{} and ¿?"

Overview
"Pen Factory” is a port of a mini-game that was originally included in Part-time Job Hell 2000 for Pico-8. The player, as a factory worker, is constantly putting caps on ballpoint pens that are flowing on the conveyor belt. There is no game over or time limit.

Game controls
Z key: Put a cap on a pen
X key: Rotate the pen to adjust the direction.

Rules
Check the orientation of ballpoint pens flowing on the conveyor belt.
Rotate the pen as necessary to attach the cap in the correct orientation.
If the cap is put on correctly, the score is counted. If you make a mistake, it counts as no score.
The game has no time limit or end condition, so you can continue until you are satisfied.

Just curious, what is the "Profile Header" in the profile settings?

But i'm not sure..

I set it to "test" to see if anything would happen.

Santa's sleigh has broken down and needs repairs! As chief mechanic, it falls to you to collect the necessary parts to fix it!

In this game you will need to venture into the floating mountain tops to retrieve Santa's Sack of Generosity, and visit the Elf Propulsion Labs (EPL) to obtain the Wonder Drive that power's Santa's sleigh.

Controls:

Move with the d-pad / arrow keys.
Jump with x.
Grab and throw items with z/c/o.

Note: to grab items you must be standing directly on top of them.

My first Picotron app! I was just having fun with animating a heart and thought it would make a nice screensaver.
For ease of customization, I moved the important properties to the top of the code, with comments, so it can be modified to your liking.
Update 1.1: Decided to add background colors, which are chosen at random at the start and when clearing the hearts!
