Cart is now currently updated to the Master branch at the main repo, and I've submitted a pull request there.

If anyone feels like the difficulty needs adjusted, let me know! Maybe you think the difficulty ramps up too slow or too fast, or a particular mechanic needs adjusted. Just note that I am completely at the token limit, so I can't really change anything except for existing values such as timers.

Looks good, but the player does a lot of moonwalking now :)

I should have mentioned that I changed my graphics section (F). Specifically, sprites (88-91) were each flipped horizontally to save a token. Could they please be updated in the master cart.

Edit: I just noticed that it looks like the top row of pixel on my game's icon is incorrect. Could that please be updated as well.

anyone have any ideas about how you make music continuously loop? how do you know when a track has finished?

P#29788 2016-10-01 07:38 ( Edited 2016-10-01 11:38)

@team_disposable: so to play music you use music"24" (where 24 is the music track #) to start it. Each music track can play up to 4 sfx tracks simultaneously. you can also select a music track to "Start loop from here" and/or "Loop after this" by clicking the looping icons top right.

here's a tutorial and I added a music-only cart below because it's probably easier to understand when you have an example:

@Scathe Thanks for the PR! I added the game, and it looks great!

@zatyka I fixed your graphics! Tell me if that looks right!

@dollarone provide a PR on github? Maybe we can fix that: https://github.com/josefnpat/pico8collab16/blob/master/collab_2/lua/07.lua

I might actually end up making another one just to help get it done. The one I did only took a day, so it's not really too big a deal, it's coming up with ideas that's the hardest part.

P#30486 2016-10-09 20:35 ( Edited 2016-10-10 00:35)

Scathe, guys. Checkowt the Atari 2600. My "KEEP" list of favs is 798 carts. That is, these are great games, good enough to play many times over.

Lots of ideas should be available to the diligent researchers of these titles. :)

I'll mention a few top from the first letters:

Haunted House
BASIC (that would be a trip to see it done w 2-buttons & arrows)
Bobby Is Going Home
Canyon Bomber
China Syndrome
Circus Atari
1-Player Combat (Hack of Combat cart)
Cosmic Ark
Cosmic Commuter (lovely game !)
Crazy Balloon
Crystal Castles

That should be enough to keep you going. :)

P#30487 2016-10-09 21:03 ( Edited 2016-10-10 01:09)

@dw you only get about 450 tokens for this though. Even most Atari 2600 stuff is well out of that range. This is maybe more like Flappy Bird territory.

P#30492 2016-10-09 21:51 ( Edited 2016-10-10 01:53)

Flappy Bird ? makes a disgusted look

Wow, Scathe ... Ok, so how about the Sinclair 1000 ? It only had 1 & 1/2 k and it had some pretty cool hits too.

I bought the system long after it lost popularity so I only knew a few games for it.

Here's a picture set though, maybe something interesting will come of this.



B&W Gameboy may have some ideas too. They had TONS of games though.


P#30493 2016-10-09 22:03 ( Edited 2016-10-10 02:04)

Ok, so I'm putting my cart here so folks know I'm merging my game next. Music/sfx is in the wrong spot, and I need to check for a dset conflict, but i'll post more details in a few minutes.

cool 2-player game. Perhaps we should make the next collabcart (if we are doing more) an exclusively 2-player game cart? :)

P#31076 2016-10-16 20:22 ( Edited 2016-10-17 00:22)


Interesting idea, but there might not be much of an audience for exclusively 2 player games.

Another idea might be to make games specifically for speed-running, and have a way to speed-run the entire cart.

P#31083 2016-10-16 21:23 ( Edited 2016-10-17 01:23)

ooh I like that! Would be awesome to go from one to another. Perhaps as levels? Either way I think it would be fun to have a theme.

P#31103 2016-10-17 07:11 ( Edited 2016-10-17 11:11)

@dollarone and @zatyka that would be neat - everyone makes a speedrunning game that connects to the next speedrunning game. Then figure out a total time for the whole cart?

hahaha, still need 3 entries for this cart though :)

P#31132 2016-10-17 23:44 ( Edited 2016-10-18 03:44)

@josefnpat That was what I was thinking. Maybe have best per-game time alongside best whole cart time, if tokens allow. Some of the persistent data could be reserved for saving high-scores.... oh the possibilities.

I'm hoping there are at least 3 more devs silently working on games for this cart. I'd probably be willing to put together another entry, but I think it's more charming to have 16 different devs working on the same cart.

I'm not done and it's not in the correct format yet, this is just to say that I'm joining.
I've got 100+ tokens left, using 1 map screen and no sounds (yet).

My thoughts on this Collab16:

  • Reservations were better: more structure and more pressure to finish
  • This was started too soon after the first one. With a break of a month or two people will forget this exists, then get hyped even more when it comes back
  • Anyone who has already made a game for this should not make another, it is much more interesting and fair with 16 different devs. There is no time limit due to the lack of reservations and I can see how this is frustrating when you submitted weeks ago, but someone at some point will make another game; have patience
P#31262 2016-10-19 19:21 ( Edited 2016-10-19 23:21)

@zatyka Those are some great ideas. I think we can drop the 3D lib for the next one, so we'll have to prototype some stuff for speedrun-cart.

I would love another entry, but I think @RhythmLynx is right; it sort of dilutes the diversity of the cart.

@RhythmLynx Nice to see your game come along!

>Reservations were better: more structure and more pressure to finish

I agree. I think for the next cart, we'll do that, but be even stricter about it.

>This was started too soon after the first one. With a break of a month or two people will forget this exists, then get hyped even more when it comes back

There was a lot of demand for this one, actually; i suspect the third won't have as much excitement, so I may have to do just that.

>Anyone who has already made a game for this should not make another, it is much more interesting and fair with 16 different devs. There is no time limit due to the lack of reservations and I can see how this is frustrating when you submitted weeks ago, but someone at some point will make another game; have patience

Yeah, I agree with this. As much as I'd like to see the cart finished, I also want to make it really diverse.

Here's my finished entry!

  • 466 / 476 tokens
  • 1913 / 3913 characters
  • sprite bank H
  • map screen U (I think? The diagram didn't seem to fit the map)
  • sprite logo / game 12
  • sounds 20-23
  • music 4-7

The music is by Robby Duguay. I used parts of Track 1: Arpument from his excellent Nine Songs in Pico-8.

I included the global function


which returns true when either button 4 or 5 is pressed. Some tokens could be saved by retrofitting the use of this function in the rest of the cart, for example in the menu, but I didn't want to mess with other people's work.

NOTE: Midnight Drive doesn't work in this version of the collab cart. I've integrated my cart into the current base cart Collab16 Cart 2 v49. Midnight Drive doesn't work in this base cart. So I've also included my cart on its own in the correct format, so hopefully it will be easy to fix. If you use my standalone cart for merging, you'll need to do the following:

* Get rid of the global music call

  • Uncomment the music call in my _init function
  • Edit this line in my _update function by removing the call to self._init(self) and uncommenting the rest:
elseif state=="complete" then
   if(btnp_45())self._init(self)--cgame=menu poke(0x5f2c,0)music(-1,1000)

P#31576 2016-10-23 17:14 ( Edited 2016-10-23 21:14)

Introducing "Boogie Bash", the game in which you play a prancing person who's having a bash not getting bashed. It's a ripoff of Mr. Space!! for iOS/Android, but that's okay, right?

  • Game/Sprite Logo: 13
  • Graphics Section: J
  • Map Section: none
  • SFX: 36-39
  • Music: 20-23
  • Cart Data Section: N/A (If only I could spare the tokens...)
  • Tokens: 474 (I think...)

Does the token count include the add(games,{name="tbd",author="tbd" or is it just the init/draw/update functions and their context? If it includes that "add" then let me know and I can try to trim down 12 more tokens. Took me about 8 hours from start to finish, and at least 3 of those hours were trying to trim it down further :(

Let me know if I'm conflicting in slots with anyone, if you'd rather I submit a pull request, etc. Just tossing this out there now to solidify my game as one of the last 2 or 3 entries.

EDIT: I noticed I was in the same game/graphics/sfx slots as RhythmLynx so I moved to open spaces.
EDIT2: My high score is 50

P#31805 2016-10-26 05:50 ( Edited 2016-10-26 11:12)

@Jamish Boogie Bash is super good! Really fun and great audio+visuals
I think the "add(games,.....)" is included in your token count
It looks like we only need one more game and for @josefnpat to sort out final merges and the cart will be complete :)

P#31835 2016-10-26 15:11 ( Edited 2016-10-26 19:11)

@RhythmLynx Thanks!!! I know I can save tokens just by getting rid of one or two of the swanky visual effects, but I already got rid of text shadows to save a dozen or so tokens and I can't bring myself to cut more. I love your puzzle game, too, I just couldn't figure out how to restart when I messed up, so I didn't get much further than the 3rd level because I was restarting each time. How do you restart? EDIT: Figured it out, seeing as how the instructions are right there. I'm dumb. 414 moves, 30 retries... at least I beat it! I really liked the music, it was slow enough that it felt relaxing and not at all repetitive considering you only had 4 patterns.

Ah, so I do have to decrease by a few more tokens in that case.

@josefnpat will you allow for a tiny bit of leeway if there are any tokens left over at the end? I can keep trying to trim it, but my eyes were bleeding out of their socket last time D: If anyone sees any obvious optimizations, I'd be forever grateful :) FYI, I'll also be snatching up another SFX and Music bank at the end as well!

P#31837 2016-10-26 15:30 ( Edited 2016-10-27 01:48)

cool game, Jamish. Starts easy but gets really hard!

I think the add(..) code is already included, but I'm not entirely sure.

P#31891 2016-10-27 05:41 ( Edited 2016-10-27 09:41)

Thanks! Let me know if it gets too hard too fast or if difficulty could ramp up faster to keep things interesting.

There is a max difficulty--difficulty scales from 4 gaps down to only 1 gap, and from 4 seconds of time down to 1 second minimum. It reaches that max difficulty once you hit a score of 50 (conveniently placed at my high score). I didn't want it to be humanly impossible at max difficulty, so I played a few times STARTING at the max difficulty to make sure it was possible to consistently score several more points before making a mistake.

Alright. Just say the word and I'll compress it more, but I'll leave it as-is for now.

P#31908 2016-10-27 14:03 ( Edited 2016-10-27 18:43)

@RhythmLynx Merged!

It's nice to see you're using music from nine songs in pico8! We need to find a way to credit him in game I think. I'm open to ideas!

Ohter than that, what a great game! And the global btnp_45() is a really good idea that I will surely add to the next jam.

I merged the cart that you merged with the v49 build of Collab16, so everything looks good!

@Jamish Merged!

I don't care if it's a ripoff, I think you've done it better! I love the dancing sprites, and the fantastic music! This is such a solid entry, great work man!

As for your question about tokens, it's everything that's required to put your object into the games table.

Here's the tokens for your game

@everyone you all rock! Only one more game to finish the cart!!!

One thing to note, to whomever makes the last game, we're nearing our compression limit, so for the release, I've stripped a bunch of comments. Don't worry if your game doesn't compress, but do worry about your tokens!

7738/8192 means there's 454 tokens left! Some folks are going over... if that's a problem for whoever makes the last game, I'll start a witch hunt. <3

P#31912 2016-10-27 16:34 ( Edited 2016-10-27 20:38)

@josefnpat awesome, thanks! I credited Robby in the 'author' part of my entry, you can see his twitter handle from the main menu.

If needs be, you could shave a few tokens from the menu update loop by using my btnp_45() function there.

P#31952 2016-10-28 08:58 ( Edited 2016-10-28 12:58)

@josefnpat Thank you for the merge and kind words! I was able to trim my tokens down while having enough to spare to add back an effect. I've submitted a pull request and I should be right at 476 tokens now.

P#31964 2016-10-28 14:44 ( Edited 2016-10-28 18:44)

@RhythmLynx sweet. I'll have to add the btnp to the header! I think that's a fantastic function.

@Jamish I saw your GitHub PR! Thanks so much! I've updated the thread with the newest cart.

7714/8192 tokens (478 tokens left)! (To reiterate; don't worry too much about compression, there's lots of comments to remove!)

P#31969 2016-10-28 18:38 ( Edited 2016-10-28 22:38)

maybe we could add a theme song to the menu as well?

I've used the old COLLAB16 graphic title, so if anyone wants to suggest a better 64x16 image, they can, otherwise I'm just going to use the old one.

I'll give folks a little bit of time to try out the cart before I finalize it!

With that, I'll probably host an xmas COLLAB16 for folks to participate in on. This time I'll use the reservation system again, but I'll have hard deadlines for those that reserve.
