This is a demo of the new cartridge storing in 0.1.6. (you'll need to update to 0.1.6 if you load this in PICO-8)

Press O (mapped to Z or C) to save the screen, and X to restore it. The cursor position is not saved.

To save, the screen is copied to the sprite sheet and then stored for clarity -- but it could have just been a straight cstore(0x0, 0x6000, 0x2000), and same again in reverse when restoring.

 if (btn(4)) then
  memcpy(0x0,0x6000,0x2000)
  cstore()
 end

 if (btn(5)) then
  len = reload()
  memcpy(0x6000,0x0,0x2000)
 end

This should also work in your browser, even if you close it and run the cartridge again. Please let me know if it doesn't!

Note that in 0.1.6 you can also cstore to separate cartridge files, meaning we can have quite large save games, and also saved data shared between carts on the bbs.

The Masks We Wear is an exploration of a social shapeshifting, attending a party in this case, where one may change their "mask" and so change their perspective and others' perceptions of themselves, in order to affect their own mood. Socialize with the other guests, check out the snacks and the music, leave when you've had enough.

Made for Ludum Dare 35 compo.

Games get harder with each level and unfortunately a lot of them will become impossibly difficult - balancing 14 games is pretty time consuming! I used 6590/8192 tokens and a decent chunk of the spritesheets (though a lot of what's there wasn't used). The screen mode hack found by sta64 forces the resolution from 128x128 to 64x64.

An entry into Ludum Dare 35, made in about 7 hours.

The theme was Shapeshift - Tetrift between the different Tetris shapes to clear both lines with just one piece! Use Z and X to change piece and Left and Right to move. Up is rotation and Down drops the piece faster.

Hi,

We are organising a coding party in Nantes (France). You are welcome to join us in the workshops and for the game jam. All of this made with PICO-8.

I would like to use black in my player sprites, how can I remap the color so that, for instance, color 12 is transparent in that sprite instead of black?
Thanks.

So if you have caps lock on or hold shift and start typing in the search bar it uses a 3x4 font! I'm guessing zep tried out other font sizes or tried having 3x5 for uppercase and 3x4 for lowercase or something, and some weird loophole means it accidentally uses the small font for uppercase characters but only in the search bar.

Elemelee

Hey, folks. First post, first video game actually completed!

Discovered PICO-8 while looking for sprite animation software, if I remember correctly, and it's been a blast ever since.

Elemêlée was a simple idea stemming from Rock, Paper, Scissors that I figured I could pull together, and I actually pulled it off! 2-player gameplay only, so bring a friend along for the battle for elemental mastery!

Arrows select the element you wish to use, button 1 to restart the battle, button 2 to bring up the key so you know which direction aligns with which element.

Even though this is pretty much done, as far as major work is concerned, I would appreciate feedback that anyone has!

Hello,

I have a Pi 2 and I was wondering if there is any way to make it automatically boot pico8 whenever I start it, as I am attempting to make it into a handheld console a la gameboy. Thank you for any help you can give.

I wonder - did anyone successfully decode the storage order within the sfx section of a cartridge? I managed to do this with the music section, but the values under sfx seem to behave very strange there, I can't find a practical pattern how the bits are distributed there.
I need to write binary data from within my python script and now I exceeded 0x3200, so this is a real show stopper for me at the moment, any help is appreciated!

Yet I know:

• each line stores 68 bytes of data
• each byte is distribute with some of its bits to several locations in this line. Filling all bytes with 255 results in a sequence of 3f77f
• there is a special "header" to each line, consisting of five bytes, which are the last ones in memory and which are not distributed otherwise

What is yet missing:

• The distribution pattern of the "regular" bytes

So apparently the raspberry pi build of PICO-8 works on the C.H.I.P.!

Game based on the Ludum Dare game I made of the same name. It's a very simple 2 player game based on Samurai Kirby and Rock Paper Scisors.

0.2 version: Basic input and flow. No Rock Paper Scisors yet.

Hello,

I have been trying to recreate Super Mario Bros 3 in PICO-8, and I have run into a bit of an issue. It would appear that solid-colored tiles don't register in the level editor. I have a fully blue (Color #12) tile in position 000 and whenever I attempt to place it in the level editor, it acts as if it is black. What should I do?

Thanks.

(There have been other rants on this topic, but most of the discussion seems to predate the move to token counting.)

So I'm brushing up against the compressed codesize limit with a cart that's barely halfway towards the token limit. It sounds like this is unusual, and from what I can tell it's because I'm commenting the code fairly thoroughly.

And I have to wonder, what is the intent behind the compressed size limit? What is it still meant to accomplish that the token limit doesn't already?

The token count is a rough representation of binary or bytecode size, which was an authentic historical constraint for many systems. It's measurable from within the editor: a coder can see at a glance how many tokens they have left and how they are affecting that number as they type. While it's approximate, it's directly correlated to code complexity, and this makes it fairly intuitive to reason about. The steps for reducing token count are also intuitive: simplify code, improve code sharing, generate data rather than hardcoding it, do more with less.

The token limit defines a scope for pico-8 cartridges; it encourages creative solutions and algorithmic content generation, and it plays off the other cart limits by discouraging tactics like offloading data into code.

Compressed code size, on the other hand, is a representation only of [i]how much entropy your source code exhibits

Clean the skies of sector Q97-C with your trusty mining laser.
Keep an eye out for debris, not to mention Turrets and Tormentors.

Controls:
Arrow keys control roll and yaw.
X-key accelerates.
Z-key fires laser.

Tips:
Full 3D navigation can be tricky, so keep an eye on your radar at the bottom.
It can be easier to sweep the laser up over targets than to try to hit them dead on.
Watch out because the laser uses your ship's power, which only refills slowly over time.

As Scathe noted over here, there's not a proper/easy-to-use Timers API built into PICO-8. Turns out it's not too hard to build one, though, so I took up the task.

The cartridge which you can play above just counts to 10. I've reproduced all the code here:

-- start timers code

local timers = {}
local last_time = nil

function init_timers ()
  last_time = time()
end

function add_timer (name,
    length, step_fn, end_fn,
    start_paused)
  local timer = {
    length=length,
    elapsed=0,
    active=not start_paused,
    step_fn=step_fn,
    end_fn=end_fn
  }
  timers[name] = timer
  return timer
end

function update_timers ()
  local t = time()
  local dt = t - last_time
  last_time = t
  for name,timer in pairs(timers) do
    if timer.active then
      timer.elapsed += dt
      local elapsed = timer.elapsed
      local length = timer.length
      if elapsed < length then
        if timer.step_fn then
          timer.step_fn(dt,elapsed,length,timer)
        end  
      else
        if timer.end_fn then
          timer.end_fn(dt,elapsed,length,timer)
        end
        timer.active = false
      end
    end
  end
end

function pause_timer (name)
  local timer = timers[name]
  if (timer) timer.active = false
end

function resume_timer (name)
  local timer = timers[name]
  if (timer) timer.active = true
end

function restart_timer (name, start_paused)
  local timer = timers[name]
  if (not timer) return
  timer.elapsed = 0
  timer.active = not start_paused
end

-- end timers code

-- start app code

function _update ()
  update_timers()
end

function _init ()
  init_timers()

  local last_int = 0
  print(last_int)
  sfx(last_int)
  add_timer(
    "timer1",
    10,
    function (dt,elapsed,length)
      local i = flr(elapsed)
      if i > last_int then
        print(i)
        sfx(i)
        last_int = i
      end
    end,
    function ()
      print("done!")
      sfx(10)
    end
  )
end

-- end app code
