I think ever since @carlc27843's Impossible Mission R.T. cart came out, people have been wondering if they could make background music for a cart using PCM synthesis. carlc27843's Emulated Amstrad CPC Chiptunes post discusses using its engine that way, @luchak has had to let people know that the RP-8 groovebox can't be used that way ... folks are curious.
I don't know a lot about digital audio synthesis, but from the conversations that have happened in the PICO-8 Discord, it sounds like there's roughly three sides to the equation:
Cost
- How many tokens and bytes are cart designers willing to give up to the soundtrack? @bikibird's Speako8 Speech Synthesis Library is under a thousand tokens - is that a good target?
- What percentage of PICO-8's CPU budget? Four voices with 25% CPU seems possible in a few different ways, but is that too much to give up to background music?



Goats, Cars n' Doors!
So...
the situation being proposed is: there are 3 doors, behind 2 of them are goats the other has a new car. you (trying to get the car) pick a door, the host stops you and opens a different door. behind that door is a goat. they then ask you "do you switch your answer".
the question: what are the odds of getting that car if you switch vs. not switching.
the problem: everyone i've asked has said its a 50% chance either way, but the answer is actually 2/3 if you switch. why? I have no idea but I built a simulation so you can answer that yourself!

I wanted to take a screenshot and draw it back to the screen like a sprite.
This is useful for screen transitions, like in Bubble Bobble where you scroll up to the next level.
The nice folks on the Pico-8 discord helped me put together this, which copies the screen to 0x8000 (the extended map location in 2.4+). Then when we want to draw it we copy it over the whole sprite sheet, draw that like a sprite, then reload the original sprite sheet.
function _init() cls() -- make something to screengrab for x=0,127,8 do for y=0,127,8 do rect(x, y, x+7, y+7, flr(rnd(16))) end end target_x, target_y = 0,0 screengrab() end [ [size=16][color=#ffaabb] [ Continue Reading.. ] [/color][/size] ](/bbs/?pid=124407#p) |

Celeste Classic collab
Mimicking the idea of collaborative map pack mods from celeste's steam release, this cart has 3 maps from individual celeste modders, assembled in the form of a multicart.
Carts
Noir
Contains a few new mechanics and has a special secret route, if you're having trouble finding it you should
Storm
A mod containing several new mechanics. While there is no secret route, there are still a few secrets hidden in various places.
Roundelie Adventure 8
A difficult puzzle focused mod utilizing some of the more obscure mechanics of celeste for beating levels. If you need some help, you can reveal the spoilers. Remember that the enter menu has a reset level button if you get stuck.
