Probably more an undocumented (as far as I know) or unexpected behaviour / feature, rather than a bug, but in case it is a bug, I'm posting it in the bug forum. This is something that people who are constructing long audio strings (>31 or 32 notes) with P8SCII should be aware of.
The point at which characters begin to be printed seems to vary; for me it's somewhere around the 40th character, which is likely around the 32nd of the notes in the string. (I feel it should be consistent in this - that always after the 32nd note plays it should drop back to printing text, but unless my tests or count are off this doesn't seem to be the case.)
The behaviour likely exists because the sfx playback is written for 32 note sfx lengths. For those who haven't read about the audio P8SCII: "If an sfx index is not specified, a non-active sfx between 60..63 is selected automatically. To fill the SFX with data before playback, the following commands can then be appended." Pico-8 manual

It is my short-time-making challenge.
I spent two nights making this cart.
You, Santa, make children's wishes come true.
Merry Christmas!

PICO-8's resolution can easily be lowered to 64x64 with:
poke(0x5f2c,3)
but it's always bothered me that you can't set the resolution to other factors of 128. So, I made this function that allows you to scale up whatever is currently drawn to the screen to any factor of 128 excluding 1 (2, 4, 8, 16, 32, 64, 128). The performance for 64x64 is pretty awful, so you're better off using poke(0x5f2c,3) if that's the resolution you're after. The others perform fairly well, with 32x32 using about <12% CPU and everything below it using <3%. One advantage of using this function is that after scaling down the currently drawn screen, you're free to draw over top it in full resolution, as demonstrated by the CPU performance text. I'm sure the performance can be improved somehow. I think this may be possible using memset, but I don't understand how to apply it to this case, or if it would even improve performance. If anyone has any optimizations, feel free to reply and I'll update the cart. Hope someone finds this useful!

Tundraine is a turn based RPG created by me; Shrumbo. In it you play as three adventurers knows as Alva, Aaron and Sam in search of the Ice Palace. Tundraine is my first full game and, though short, is as detailed as I could make it taking three or so months to craft the systems, art, code, and music. I really hope you enjoyed and I you want to follow me as I make other thing go to my discord and YouTube channel linked below.

A PICO-8 version of a "falling sand" materials simulator, including sand, water, stone, wood, fire, acid, gunpowder and smoke!
Controls:
- Left mouse button / x: Paint material
- Right mouse button / o: Clear materials
- Click the palette on left to select material to paint
- Slider on bottom left sets tool size
This is based on bits I remember from a talk given by the creator of the game "Noita," and the clever types of materials and behaviors from that game.
To make this run acceptably in pico-8 it only simulates in portion of the screen size. Positions and materials are represented by a pico-8 color in a Lua table of fixed positions. Materials behavior is in update60() and should be easy to hack for fun. _draw() does a little bit to make flames flicker. Since the world simulates bottom-to-top, rising materials like smoke get carried along with the update and move very fast because they 'ride' the update direction.

Update 220224
- Minor bugfix on two items
- Added 1 pixel movement buffer. It didn't feel too stiff on analogue stick, but I noticed the cornering was stiff on d-pad.

A present-pushing puzzle game!
As a courier at Northstar Gift Delivery Co., it's your job to deliver all the gifts to the targets on each level. "Preferably in the fewest amount of steps possible," your boss is quick to add.
Use the arrow keys to move. Press Z to undo your last move, or X to reset the entire level.
The game contains 8 levels and was made for PICO-8 Advent 2021.

A short game I made in one week for a Christmas-themed game jam in my technology class.
You control Santa, and you have to collect as many presents as possible in 90 seconds (1.5 minutes) without collecting any coal, to get a high score!
Controls: Arrow keys for movement, and X/V to run. Assuming you use default keyboard controls, of course.
Art, code, and music/SFX by me.
Thank you for playing!

A couple weeks ago I bought pico-8 to try and learn lua, but now I am stuck with the old version because it's not showing in my purchased products page. Any ideas? (I didn't use the weird 3rd party purchase save thing)

TO LOAD THIS PICO-8 CART in immediate mode, type:
load #newfont2021
color(8) ?"Now is the time" color(9) ?"for all good men" color(10) ?"to come to the" color(11) ?"country." |
After some very thorough digging I did manage to find a few Piconians making use of the new ability to change the system font to another, yet none of the explanations seemed really simple to follow.
So once I finally understood - I thought I would toss my hat into the ring to show an easier way to replace the default 5x3 font with a new 8x8 font - which is included. See the source for details.

Since the introduction of large maps, I think there's one feature missing that would help many pico-8 games: the ability to flip and rotate individual tiles in the map. Games often use up a lot of their sprite space just for the map data, duplicating tiles for the different boundaries needed, or using manual spr() calls to get the necessary x_flip and y_flip needed. Since there's no visible editor to worry about anymore, this could be a quick patch (via a poke value to an alternate map() drawing mode), and would make map() much more useful.
Flip map mode, option one: 0x8000+ is used for map data (same format used now), 0x2000 is the flip data for that map data, using 2 bits per tile (x_flip, y_flip).
Flip map mode, option two: the 1 byte of map data stored anywhere now references a cell # in the first 16 sprites (n 0-15, 4 bits), x flip (1 bit), y flip (1 bit), and 90 degree clockwise rotations (2 bits). Like so:
map data: 1 byte per tile (same as now) nnnnxyrr nnnn = sprite number, 0 to 15 [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=103189#p) |

I'm working on a platformer game. I'm having an issue with enemy AI.
I want that the enemy will turn the opposite way once it reaches a cliff, much like a collision with a wall.
I want to make a collision check that will check if the floor of the tile after the enemy doesn't have any flags.
How do I do that if 0 means the first flag?
