Wobblepaint started as a secret cartridge in my 2019 Advent Calendar entry, but I think it's time for a proper release! This version has some extra controls and nicer, less crinkly wobble.
Instructions
Your brush has a size, colour, pattern and shape that can be adjusted separately. There are 4 presets you can select and modify using keyboard shortcuts, or by clicking and dragging the top menu bar down to reveal a palette of attributes.

Hi All! PICO-8 0.2.1b is now up on lexaloffle, Humble, itch.io, and for PocketCHIP. This update started as a continuation of 0.2.0 bug-fixing work, but I also relaxed my position on API minimalism just enough to add some new features :D
UPDATE: 0.2.1b is now live and fixes the print() bug, and a few other things. See the changelog below for details.
Ovals
You can draw ovals (technically, ellipses) both when running a cartridge, and when using the shape tools in the graphics/map editors. Ovals are specified by their boundary rectangle, and follow the usual draw state rules.
pattern={[0]=
…,∧,â–‘,⧗,â–¤,✽,★,✽,
ˇ,░,▤,♪,░,✽,★,☉,
â–‘,â–¤,♪,â–‘,✽,★,☉,…,
∧,â–‘,⧗,â–¤,✽,★,✽,★
}
function _draw()
cls(1)
for i=0,31/32,1/32 do
local x=64+cos(i+t()/8)*48
local y=64+sin(i+t()/8)*44
local w=8+cos(i*2+t()/2)*6
local h=8+sin(i*3+t()/2)*6
fillp(pattern[i*32])
ovalfill(x-w,y-h,x+w,y+h,
(i*32)%8+8)
end
print("pico-8 0.2.1",40,62,13)
end

Shibuya Pixel Art 2020 is accepting submissions until the end of June, and this year there is a new category for 128x128 games! Lexaloffle is sponsoring the game category with a prize (a Picade Cabinet), and by offering a limited number of PICO-8 licenses to participants.
Similar to a game jam, entries should be based on one or more of the following themes: Shibuya, AI, Humanity, Game and/or Landscape. Unlike typical game jams, existing work can be adapted or reused, as long as it did not win a previous contest. You can find previous winning entries for 2018 and 2019.

Back to 2016! This is a demo @castpixel (also on twitter ) and I made in the weeks leading up to Tokyo Demo Fest 2016, as newly formed group: POD. Because it was made in a hurry, I felt I should tidy up the code before posting it. But that's never going to happen, so here's an even messier post-compo version with a few extra details added instead! The rotating orbycube effect can now be found in /demos though if you'd like to see roughly how it works. Also, if you're curious you can find the compo version with: load #orbys_compo

Download 0.2.0i at lexaloffle or via Humble, or for PocketCHIP.
Alright, let's do this! PICO-8's core specification is complete, and it appears to do what it says on the tin. So I'm calling it:
PICO-8 is in Beta!
The main purpose of 0.2 is to finish freezing the core of PICO-8 -- the api, cpu counting, specs, cart format, memory layout, program behavior, backwards and future-compatibility should no longer change.
Earlier attempts at settling on a fixed core in 0.1.11 and 0.1.12 failed because of technical issues creeping in and also some design decisions that just didn't sit right. It has only been due to the ongoing process of users like @Felice, @electricgryphon, @jobe, @freds72, @Eniko, @samhocevar, and many others prodding at the boundary of what PICO-8 can do -- and what it should do -- that all of those nooks and corners finally took shape. I'm really happy with the way the last pieces of PICO-8 have snapped together, and I think it has reached a point where it feels not only like it should never need to change, but that it never could have been any other way.

Merry Christmas and Happy Holidays everyone!
This is my cartridge for the 2019 Advent Calendar. It is a simple toy/game with no secret endings at all. Nope.
There are 26 (or more! wink wink) carts available now, and you can get the full experience by playing from @enargy's main cart. It is a truly joyful collection!

The BBS's media storage system has recently been updated, and image attachments are now sent to a cloud bucket. Let's stress-test it with some gifs!
Rules:
- No gif, no post!
- No explanation of the gif is required.
- No quality required.
To save these, I used "CONFIG GIF_SCALE 3" from the PICO-8 command prompt, but any size is ok.
Some of these are doodles, some are unfinished carts, some are abandoned projects that will only live on as gifs.

At the start of each level there is a shop. You can spend hearts on 3 things:
- Blocks: use these to build bridges, barriers, and to clobber monsters.
- Jetpack fuel: press and hold jump while in mid-air to use your jetpack.
- Gems: become your final score.
Life is replenished on completing each level.
Monsters also drop fuel and blocks sometimes.
You can modify your block placement with up+left/right etc.

PX9 is a lightweight gfx & map compression library, intended to replace PX8. It uses the same ideas and interface as px8, but is smaller (297 214 tokens to decompress), and requires zero configuration.
To compress some data:
px9_comp(x,y,w,h, dest_addr, vget) returns the number of bytes written x,y,w,h is the source rectangle (e.g. on the spritesheet or map) dest_addr is where to write it in memory vget is a function for reading values (e.g. sget when compressing from spritesheet) |
To decompress it again:
px9_decomp(x,y,src_addr,vget,vset) x,y where to decompress to src_addr is a memory address where compressed data should be read from vget, vset are functions for reading and writing the decompressed data (e.g. pget and pset when decompressing to the screen) |
Unlike px8, the vget function does not need to return 0 when x,y are outside the destination rectangle
Workflow
You can use px9.p8 as a utility for compressing other carts' data by replacing _init() with something like this:
reload(0x0, 0x0, 0x2000, "mycart.p8") clen = px9_comp(0, 0, 128, 128, 0x2000, sget) cstore(0x0, 0x2000, clen, "mycart_c.p8") |
This would compress the spritesheet from mycart.p8 and store it in the spritesheet of mycart_c.p8, using memory from 0x2000.. as a temporary buffer. See the PICO-8 Manual for more information about reload() and cstore().

Update: Download 0.2.6b for CHIP and PocketCHIP here: pico-8_0.2.6b_chip.zip
You can just unzip it somewhere and run it, but if you want to install over the default location so that the launcher buttons still works, open Terminal and type the following:
wget www.lexaloffle.com/dl/chip/pico-8_0.2.6b_chip.zip sudo unzip pico-8_0.2.6b_chip.zip -d /usr/lib |
(the default password is: chip)
Update: I've seen instances of the launcher button pointing to both /usr/lib/pico-8 and /usr/lib/pico8. If you're still getting some older version when using the launcher button (check the boot screen), use:
sudo mv /usr/lib/pico-8 /usr/lib/pico8 |
This is the first time I've released a build for CHIP, as they were previously handled by the late Next Thing Co. In 2016 I spent a week at their workshop in Oakland, hacking out a proof of concept along with the first version of SPLORE, so that we could see how it would all fit together. It was not a large company, but everyone I met there were stand-up hackers driven to make something new and interesting. It's remarkable what they were able to achieve, and I'm glad to be able to contribute to the legacy a little by continuing support for these devices.

Hey PICO-8 people! Builds for 0.1.12 are now live on Lexaloffle and Humble. UPDATE: PocketCHIP users can get it here.
If you just want to see what's new, please scroll down a bit. But first of all, I should issue a..
Breakage Warning!
Future Compatibility: You'll need to update to 0.1.12 to play cartridges made in 0.1.12 or later. This update is another attempt at eternal future compatibility (can handle any future carts). There were a few bugs in 0.1.11g that needed a cart version bump to fix, and so I also took the chance to tweak the API (more on that below).

This is a replacement for print() that draws a customizable 5x6 font. It encodes each character as one number, and then loops through each pixel checking to see if that bit is set. So it's not very fast, but is handy if you just want a quick solution for some text larger than 3x5.
Cartridge for generating and testing font:
The spritesheet and the convert() function is not needed in the release version of a cart. Paste the following snippet into your code (and optionally replace fdat with your own data):
fdat = [[ 0000.0000! 739c.e038" 5280.0000# 02be.afa8$ 23e8.e2f8% 0674.45cc& 6414.c934' 2100.0000( 3318.c618) 618c.6330* 012a.ea90+ 0109.f210, 0000.0230- 0000.e000. 0000.0030/ 3198.cc600 fef7.bdfc1 f18c.637c2 f8ff.8c7c3 f8de.31fc4 defe.318c5 fe3e.31fc6 fe3f.bdfc7 f8cc.c6308 feff.bdfc9 fefe.31fc: 0300.0600; 0300.0660< 0199.8618= 001c.0700> 030c.3330? f0c6.e030@ 746f.783ca 76f7.fdecb f6fd.bdf8c 76f1.8db8d f6f7.bdf8e 7e3d.8c3cf 7e3d.8c60g 7e31.bdbch deff.bdeci f318.c678j f98c.6370k def9.bdecl c631.8c7cm dfff.bdecn f6f7.bdeco 76f7.bdb8p f6f7.ec60q 76f7.bf3cr f6f7.cdecs 7e1c.31f8t fb18.c630u def7.bdb8v def7.b710w def7.ffecx dec9.bdecy defe.31f8z f8cc.cc7c[ 7318.c638\ 630c.618c] 718c.6338^ 2280.0000_ 0000.007c``4100.0000`a001f.bdf4`bc63d.bdfc`c001f.8c3c`d18df.bdbc`e001d.be3c`f3b19.f630`g7ef6.f1fa`hc63d.bdec`i6018.c618`j318c.6372`kc6f5.cd6c`l6318.c618`m0015.fdec`n003d.bdec`o001f.bdf8`pf6f7.ec62`q7ef6.f18e`r001d.bc60`s001f.c3f8`t633c.c618`u0037.bdbc`v0037.b510`w0037.bfa8`x0036.edec`ydef6.f1ba`z003e.667c{ 0188.c218| 0108.4210} 0184.3118~ 02a8.0000`*013e.e500]]

Hey look, it's a Voxatron update!
Builds are live on lexaloffle and Humble. If you have trouble accessing your account, see this page. If you own only PICO-8, you can now update to the Voxatron + PICO-8 bundle for the difference of $5 here.
This update folds in a lot of fantasy console work, and is the first time you can see Voxatron in something similar to its final form. It has the usual trappings of a fantasy console: carts with labels (and matching .vx.png file format), a boot sequence, a SPLORE-like interface, virtual cpu limitations, and most notably, a Lua scripting API. The API is a superset of PICO-8's one and can be used to write PICO-8 style programs from scratch, or mixed with built-in engine features.
[A note for returning Voxatron users, including "Humble Voxatron Debut" customers: you can also download PICO-8 with the key that you originally purchased with. And if you don't know what PICO-8 is -- have a quick look here because it is very relevant for this update! PICO-8 started as a playground for Voxatron's scripting system, but grew into the fantasy console concept that this update is based on.]

Ring all of the bells in each level to progress -- but be careful not to stand too close!
This cart is my contribution to the Advent Calendar 2018. I think it turned out well as a wee concept game, but it's really the equivalent of a hastily wrapped box of chocolates purchased at 3am on Christmas morning from the closest gas station, compared with the amazing work that can be found in the calendar. Try out the other 24 games here if you haven't already:

I never imagined I'd be excited about releasing a website update, but here it is! This update addresses many ancient bugs and issues, but also aims to support the PICO-8 / Voxatron fantasy console ecosystem. There are new features to make collaboration, sharing, teaching and exploring carts a little easier.
lexaloffle.com is now also running on a new server, on top of a leaner stack that should be much more responsive. Along with a lot of new code running underneath it all, there will still be some new bugs to deal with (apologies to those who were around earlier this week for the bumpy migration process!) -- feel free to report any issues in the comments here, or in the PICO-8 bugs sub-forum.
New Features
Superblog
View a feed of everything going on using the Superblog. You can also follow other users to create a tailored feed.
Featured Carts
The list of featured carts (same as in SPLORE) is now sorted by the time each cart was added to the list, so that it's possible to come back periodically and see what's new without digging too much for notable releases. Selection will be based on a combination of user interaction, manual curation, and the phase of the moon. To kick things off, the first few pages of the old featured lists will be fed through a few carts per day.

Hey Everyone! PICO-8 0.1.11d builds are now live on Lexaloffle and Humble! We are still working on CHIP / Pocket CHIP builds -- I'll update this thread when they are live. [Edit: they're live now with 0.1.11g]
Welcome to the Core
Despite the unassuming version number of 0.1.11, this update marks something of a milestone: The core of PICO-8 is now feature-complete, with API and specifications that are likely to remain fixed. Before it becomes entombed as a read-only blob of C code however, there is still some time before beta to address any issues that crop up. Let's see how 0.1.11 works out and what points of friction emerge.
One of the goals of PICO-8 is to create a stable, familiar medium in contrast to the shifting sands of modern software development. Instead of growing by changing the core of PICO-8 over time, I'm aiming to settle on a minimal, eternal component that can be built on top of (improved tools and bbs integration), extended sideways (extra ports / host platform support), built out from the inside (making useful snippets and carts!), and around (nicer BBS, cartverse, documentation, resources and community events).
v0.1.11 is also the point after which PICO-8 and Voxatron co-development start to part ways -- Voxatron's API and specification is a superset of PICO-8 v0.1.11's. The upcoming Voxatron update looks basically like a 3D PICO-8, with its own version of splore, png cart format, labels, and bbs integration. I messed up the Voxatron release plan partly because of committing to this -- but more on this later in a separate post. o(_ _)o
Many thanks to the numerous PICO-8 users who helped iron out bugs in the 0.1.11 release candidates. I snuck 0.1.11 out via twitter thinking it was pretty solid, but it took 3 more builds to get right. If you find any old carts that don't run or behave strangely, please ping me on twitter, or better still, post a bug report in the support forum. There will be another follow-up (0.1.12) to catch any left-over issues. After that it will be onwards to beta (0.2.0) \o/

A heads up for Voxatron users -- the first version of the Lua api will be out next week in 0.3.5!
Pictured above is the result of drawing voxels directly into a room's map. The 0.3.5 api also provides access to actor attributes and state, spawning, camera control, and direct access to the display. The entire PICO-8 api is in there with some 3D counterparts (line3d, box, sphere), and it's possible to import a pico-8 cart into the resource tree, place it in a room, and run the cart on a single slice of the display. The .p8 cart shows up in the resource navigator, and is placeable in the room like this:
The code can also be edited to make slight adjustments for the 3d display:
In other news, I've updated the website with mobile-friendly cart listings and touch controls for the carts. It's still a work in progress -- the sound in particular is very choppy or missing altogether. But apart from that it is quite useable. If you have a modern phone or touch device please try it out!

Hey All -- PICO-8 0.1.10 builds are now live on Lexaloffle and Humble!
Update: 0.1.10b is up with bugfixes for the html exporter. (Changes)
Update2: 0.1.10c is up with fixed atan2()
Multicart Exporter
The EXPORT command can now be used to create a single .js (and .html) file that contains more than one cart. All of the carts can read, write, and run each other as if they were local files loaded from PICO-8. To do this, add the names of up to 15 extra cartridges you'd like to include in the export: (.p8 format only in 0.1.10)
> LOAD MENU.P8 > EXPORT MEGACART.HTML JELPI.P8 DRIPPY.P8 CAST.P8 |
Inside the program, you can then use RELOAD() to grab data from other carts:
-- GRAB JELPI'S SPRITESHEET RELOAD(0,0,0x2000,"JELPI.P8") |

PICO-8 0.1.9b builds are now live on Lexaloffle and Humble.
This is a bug-fixing update, mostly for crashes related to switching between widowed mode, full-screen and minimized windows. I've also included the dynamically linked pico8_dyn versions in the linux archives, that were missing from 0.1.9.
The Windows installer & .zip file include a more recent sdl2.dll, although there weren't any known issues relating to that.
I've switched back to shift-a..z for glyph entry in the code editor, as alt-a..z is sometimes reserved by the host operating system. If you find yourself accidentally entering the extended characters by accident, you can turn this off in config.txt (near the bottom). To enter glyphs without shift-a..z, press ctrl-k to toggle glyph mode.
Changelog:
v0.1.9b Added: Alternative function key mapping: ctrl-6..9 for F6..F9 Added: Alternative glyph entry method: (ctrl-k) to toggle glyph mode Changed: Enter glyphs with shift a..z, but can be disabled in config.txt Changed: Increased emscripten ram to 128MB (some carts at risk of running out) Fixed: Crash when window size is tiny or minified Fixed: Crash on toggling fullscreen mode Fixed: printh can write files outside filetree (security issue) Fixed: show_fps (can also now be toggled with ctrl-1) Fixed: Shorthand if/then syntax error when using the form: (functionname)(param) Fixed: log.txt not saved in path specified by -home switch Fixed: Default application data folder created even when -home specified Fixed: Missing dynamic builds (pico8_dyn) from linux archives Fixed: Removed unneeded RPATH from linux binaries Fixed: export foo%d.wav fails to write multiple files |
