Picotron out of memory ~IFF running from the IDE~ anytime

Sun, 31 Aug 2025 20:16:30 UTC

Hello! Me again.
I've been working on a large project, and have recently run into an "out of memory" bug... that only happens if I'm running the cart from the IDE. Even if I exit the program at the very first line, I can't run it with CTRL+R without getting an "out of memory." But, (if I remove that line of course) I can run the program from the desktop, by manually clicking on it and running.
Are my files too big? What's going on?
I would happily share the cart, by the way, but I'm not sure if I can for legal reasons. It's a demake of Balatro and it's far enough along that I don't know if I should risk it.

EDIT: After going along with this for about 10 lines of code, this no longer works, and it pulls an "out of memory" constantly. Checking stat(0) reveals I'm only using a few hundred KiB (when I remove a few dozen lines of code at random to get it to run, nothing essential or large though

Picotron Anywhen recovery bug?

Sat, 16 Aug 2025 16:55:51 UTC

Hey everyone!
I was working on a demake of Balatro, and was testing out some functions by running the card over and over, when it suddenly started reporting a "memory overload." It wouldn't run, until I restarted Picotron. But when I loaded it back up, all my sprites were completely missing! Not just corrupted, but completely blacked out.
Of course, I have anywhen running for times like these, so I load up a previous save and... huh?

No matter what I do, anywhen can not load any previous file. Either I put in only a date, and it tries to load from 5AM (which has no file), or I put in an exact time, and it searches for a completely different one. In fact, most dates I put in end up with Picotron searching for this exact date in the picture: Aug 17, 01:48:17. Not only is that not what I typed, it's actually in the future!
Now anywhen is saving my deltas, probably correctly. As seen below, I'm actually putting in times that align with real supposed saves (adjusted for 4-hour time zone in the above picture, but even without it it returns the same result)

None of my other carts have been affected in any way.
Anyone else experience this? Is there anything I can do to get my sprites back? I put a lot of time into them. :(

EDIT:
Worth noting this is on the 0.2.0h version

Hardest Challenge!!

Hello everyone, and welcome... TO YOUR DOOM!
Above is the most difficult challenge I believe has ever been posted on the internet. Inspired by many other difficult challenges you may have seen online (I know I've certainly seen quite a few!), this game is the natural conclusion to all of them.

Let's break down the challenge.

First, you need to get the button to appear. This only has a 1% chance to happen on start-up, so needless to say, we're starting off pretty strong.
Next, you need to actually press the button (with X or Z). However! This sneaky button only has a 1% chance of being press-able, and has a 99% chance to troll you!
The challenge doesn't end there, though. After that, the button actually has a 99% chance of making you lose! Only 1% of the time will this button cause you to win, marking the end of the challenge.

Now getting into... the MATH (I know, I know), we can see that any run only has a 1% * 1% * 1% = 0.0001% chance of making it to the end! That's, quite literally, one in a million! Now THAT'S some serious challenge. I'd like to see anyone try this!

One last thing

.... Good luck >:)

PICO-8 Line Algorithm?

Fri, 31 Jan 2025 01:07:36 UTC

Hey all!

I was wondering if anyone knew what exact line algorithm PICO-8 uses. It isn't documented anywhere, and curiosity has led me down a few rabbit holes, so at this point I figured I'd just ask. I don't think it's Bresenham's line algorithm, but it seems pretty close?

Desert Plus 1.0

Z - Honk

Welcome to Desert Plus, the sequel demake to the critically un-aclaimed Desert Bus!

The original

Desert Bus is one of the 6 planned games for the unreleased Sega Genesis game Penn & Teller's Smoke and mirrors. Most of Smoke and Mirrors's games were intended to trick one of the people playing it. Multiple games involved secretly cheating in a 2 player game, but this one is build to enrage the player through monotony. The objective?

Drive from Tucson, Arizona, to Las Vegas, Nevada in real time.

360 miles. A maximum speed of 45 miles per hour. A slight pull to the right. Don't drive off the road, or you'll be towed back to the start, also in real time. Just 8 uninterrupted hours of you, and the road.

What makes this version Plus?

Desert Plus is my PICO-8 demake of Desert Bus, named "plus" not only for the obligatory "p" cameo, but because of all the new content!

New Content?

Uhh.. yeah! There's tons of new content! Like um. The time is local to your timezone, and the palette changes with the time of day! Plus there's fewer things on the road! That's a feature. Not a bug. There is no bug either. Or is there?

...

Enjoy the ride.

Lines from off screen dont work

Wed, 27 Jan 2021 01:35:55 UTC

Steep enough lines aren't rendered correctly when they originate off screen

This code should draw a completely solid screen. It does not.

cls()
for i = 0,260 do
line(i,127,i-5,0,1)
end
