I am extremely confused as to how I would go about uploading a pico-8 cart.

Info for doing it with files and with "save @clip" would be appreciated.

As for using "save @clip" I'v tried just copying the commandline but it still doesn't seem to be working.

submit button guides you through that. after you upload, make a post with the cart, ie. [#cart-id#]

That might be helpfull but I don't even get that far I trie to copy and paste "save @clip" but it just says that the cart is invalid.

By the way how do I access the .p8.png file for a cart?

type folder in the pico-8 command line, and it opens where your carts are saved, but you probably need the folder location. straight from the manual:

    The default location for PICO-8's drive is:

    Windows: C:/Users/Yourname/AppData/Roaming/pico-8/carts
    OSX: /Users/Yourname/Library/Application Support/pico-8/carts
    Linux: ~/.lexaloffle/pico-8/carts

Can you record a gif (use F9) of what you’re trying?

Load a game, type 'save @clip', then copy in another program, game should be there

Here it is,

No sorry here it is:

I meant a GIF to show what you’re doing in pico-8 :)

You have to use 'choose file' to upload a PNG cart from your computer, or paste what you get when you type 'save @clip' in the pico8 console after loading your game.

this is what I get.

Great, so paste it in the correct form field then post!

in the shell export a png with the code:

SAVE xyz.P8.PNG

this you can upload then.
