Here's SPY'S DEMISE (an old Apple ][ game) in a TweetTweetCart!

CONTROLS: Arrows right and left. Avoid RedFaces, climb ladders to get to Star!

Once you start moving, you can't stop until the edge, so keep steering to avoid RedFaces!

WORLD RECORD: @Tleprie on Itch.io, 41.66!

Have fun!

(Added a restart for un-minified cart!)

Hi,

I've made a background for my game using tline, and while it works on windows, the exact same cart ran on the raspberry pi displays nothing, just black background.

I've tried on both Windows and Raspberry Pi using the latest 0.2.0h build of Pico-8.

Is tline not available on the Raspberry Pi? Or is this a bug that will be fixed later?

Many thanks

It's the fourth TweetTweetJam! My entry for this Jam is a stripped-down OutRun clone in 559 characters.

There's a couple things I'm proud of in this cart, so I'm posting an annotated, less-minified version of it below.

I mean...when we hit version 1.0.0 or so, we could make a game compilation/port for the Nintendo Switch. Just for the sake of fun and having more hardware to work with.

What do you all think?

My second entry for TweetTweetJam 4. Chars used: 560.

Rules

Guide your guy to exit ▤stairs while avoiding the 🐱enemies and collecting ♥hearts & ◆picogems.

You can wrap around the edges of the screen - use this to your advantage for stylish dodges and pickups! Though beware: enemies can do this too. Watch your back :)

On each floor, an additional enemy/item will spawn.

Controls

• [⬆️⬇️⬅️➡️] Move

My high score on the final version is about 70◆.

This game was originally intended to be like Zelda, but ended up being more like Robotron without a gun. Enjoy.

Hey @zep,

So we've discovered that 0x5f5e is a destination write mask if it's between 1 and 15, such that the write is now presumably something like this:

dest = (dest & ~writemask) | (color & writemask)

It'd be really great if the top four bits of 0x5f5e were a read mask, allowing us to select bitplanes from source pixels/colors:

dest = (dest & ~writemask) | (color & writemask & readmask)

This would be nice for packing fonts and such. It's already doable with pal(), that's true, but you have to set the entire palette to make it work, whereas you could set just the relevant colors with a read mask. Like, if you have a 1-bit font encoded into four layers, and you're picking the second layer, you'd only need to set pal(2,col) to make it work, instead of all 16.

When I click the pencil in the new pattern / SFX mode of the pattern editor, I can't immediately copy the SFX by pressing ctrl-C (even though it says "copied 1 sfx")

Just upgraded from 0.2.0d and this has mysteriously stopped working. No changes inside PICO-8, no errors. Don't see a mention of anything that could affect this in the changelog, so I assume it's unintentional?

Hi PICO-8 community!

A couple of years ago, I found a puzzle game called "Star" in Rockbox - an open source media player firmware. It was a simple puzzle game in a 16x9 grid and re-creating it has been on my TODO list for about as many years as it seemed like it should be easy, plus I really enjoyed it (it's a bit like Sokoban).

Some reading revealed that it was already a remake, the manual said the following:
> It is actually a rewrite of Star, a game written by CDK designed for the hp48 calculator

Looking for the original got me to a Java (in the browser) version of the game, which didn't work because it's 2020 and... well, Java in the browser. A 5 minute attempt to get this running outside of the browser on MacOS was fruitless and I abandoned it because meh.

I've decided that I'd like to give this a go in PICO-8, which I bought for this purpose. I'm okay (not my day job) with writing code, but have zero experience with game development. The source for Star on Rockbox is

Hi. To make a long story short, I've been trying to get PICOPi to work on my Pi 3.
Yes, I did get the right version of PICOPi, but Pico-8 wouldn't boot up for some reason.

This was happening with the 0.2.0d version, but I wonder if it's already fixed by now.

For those not in the know, PICOPi is a buildroot-based image. The website disappeared recently, but apparently you can access it through the Wayback Machine or something.

It's a pacifist endless space-harrier demake for pico-8, you can;t shoot but must avoid ground obstacles and projectiles (from invisible enemies!)

I've been looking into building a portable PICO-8 recently, so I'm going through display component websites for a square or nearly-square screen. This website (link) has a 60fps, 4" square touch display, so I was wondering if anyone has any experience with the company, Pimoroni.

They mention on the store page that it "works really well for Pico-8 games", which I think is pretty great, if it's made specifically for what I want to build. I thought @zep mentioned somewhere recently that he was looking for a square screen like this, too, so if the company is good then this may be a starting point for an official PICO-8 portable?

Here's a short video clip of the display in use that I found on another website. Pimoroni seems to be a reseller, but they've added code to get it working on Raspberry Pi, and I can't find anything online about "HyperPixel" that doesn't link back to them. I'm new to builds like this, so if anyone has experience with these kinds of projects, I could use some advice.

TweetTweetDevour is a simple game developed for tweettweetjam-4

My game

This is my first game and I am pretty proud of it.
I have worked on it to make everything work a lot, because I am all new to pico8. Any comments will be apreciated

"Plot"

You are a monk in search of his true self by crossing desserts, and drinking water.
You need to cross a dessert inhabtated by snakes and bad foxes. An idiot put some spikes to make your life easier.

How to play

It isn´t complicated. You just have to drink water regularly and avoid getting hit by animals or spikes
You can use the sword to kill animals. You can kill with the initial sword up to 2 animals

Tips

Try to drink water regularly and try no to go to fast, because thats how yo get killed. The water obliges you to move but you have 30 secinds for each jar you drink, so don´t worry

A game made in 560 characters for TweetTweetJam 4. The sound effects are generated from the poke commands at the top. The note pattern is random and can be a little unfair at times. I wanted to try a smarter way to generate the notes, but with 560 characters, there's not much room.

Z or C - Top line
X or V - Bottom line

If you're looking for a more readable version of the source code, check the spoiler:

-- The Poke commands generate the music, poke4 creates the first two notes
-- the first poke2 creates the third note (when you miss)
-- the last poke2 sets the speed of the notes (16)
poke4(0x3200,0x5ba4.380c)
poke2(0x3204,0x6911)
poke2(0x3240,0x1001)
c=0  -- combo count.
h=0  -- high score.
t={} -- notes in play.
m={} -- flags if you hit a button and missed a note (for both bars).
o=0p=0 -- delay between note generation, so 40 of them don't stack on top of each other.
_set_fps(60) -- set fps to 60, so the scrolling doesn't look awful
::e:: -- normally, gotos are ugly, but for code golf, they're a necessary evil.
-- clear screen and render the bars. A rectangle generates both lines.
cls()
rect(-1,56,128,72)
circ(15,56,4)
circ(15,72,4)
-- reset and tick down parameters for next frame.
p-=1o-=1m[4]=1m[5]=1
-- generate a note randomly, if it's created, add delay until next note (p and o).
if(rnd(25)<1 and o<0)add(t,{x=127,y=53,b=4})o=12
if(rnd(25)<1 and p<0)add(t,{x=127,y=69,b=5})p=12
-- loop over each note, see if it was correctly played, missed, etc...
for i in all(t)do
i.x-=1 -- come on down, you're the next contestant!
?"♪",i.x,i.y,12 -- draw the note
-- if note was played inside the circle, play the sound, 
-- remove it from play, and signify the player didn't miss,.
if(btnp(i.b)and i.x>=8 and i.x<=20)sfx(0,0,i.b-4,1)del(t,i)c+=1m[i.b]=0
-- if the player missed. remove their combo, play the missed note sound.
if(btnp(i.b)and m[i.b]>0)sfx(0,0,2,1)c=0
-- if the note left the screen, remove it from memory.
if(i.x<0)del(t,i)c=0
end
-- if the current combo is higher then the old one, add it to the high score.
if(c>h)h=c
-- print hud
?"combo: "..c,5,5,6
?"high: "..h,90,5
-- render the crowd, have them dance to the left and right depending on the note hit.

This is a simple golf game, with procedural courses spanning a bunch of islands, I guess. Get to the hole in as few strokes as possible!

Watch out for water! Should you land on the green or in a bunker your shot power will be reduced.

Controls

• [⬅️➡️] Aim
• [🅾️❎] Swing (hold to charge power!)
