I wanted to download an older version of one of my carts and didnt save the cart number or add it to my cart thread. I couldn't find a good way to navigate the BBS to find my old carts. So I downloaded them all (AFAIK) up to 7/22/18.
Here's a link to them all: Download

Let me know if I missed any.

That file wasn't as big as I expected, given the current cart ID.

Do some of them simply not exist?

Or am I wrong in assuming you downloaded everything by writing something like this:

for i=1,#carts do
  download(i)
end

Cart #54407 | 2018-07-25 | Code ▽ | Embed ▽ | License: CC4-BY-NC-SA

(use the pause menu to get the cart number and/or try another one)

I used c# webclient and went through the web. And yes some of them just dont exist.

I didnt even think of using pico-8! (duh!)

@spencifier: AFAIK you couldn't do this with pico-8 anyway. load() also runs the cart so you couldn't save it with code. Felice's post was pseudo-code for what you actually did and the cart I posted was just a semi-related random thought :)

iirc there was a big jump in cart IDs at least once. I stopped maintaining my own crawl shortly after. Glad to have an updated archive for testing purposes! :)

I'm entirely certain there's some garbage collection going on for carts which don't exist in posts/threads anymore. If you want to keep your old versions accessible, you need to stuff them in a post somewhere, Presumably the bottom of your main thread post in a little hidden spoiler area would be ideal? I think that having multiple carts in the same post keeps all but the first one from showing up in splore, anyway.

I'd be curious to see an EXE that does download every single PICO-8 cartridge to put into a backup directory. I know we rely on SPLORE, but when if and when it goes down ?

So, uh, has this been updated with new carts? I'm building my retropie pico8 box and I'd love it to work offline.

Time to revisit this. I started using tac08 on my rg350 and wanted to download a few carts. So...I made a small python program that will find and download all carts. As of writing this, there are 8,478 carts (150MB)

Credit and details on how to do this is here: https://www.ebartsoft.com/pico8

python3

import requests

from io import BytesIO

CART_DOWNLOAD_DIR = os.path.dirname(__file__) + "\carts"

def save_cart(cart_info, data):
    # Remove invalid filepath characters
    filename = "".join(x for x in cart_info[1] if x.isalnum())

    # If two carts have the same title add on the carts unique name.
    if exists(CART_DOWNLOAD_DIR + "\\" + filename + ".p8.png"):
        filename += "." + cart_info[3]

    # Write cart data to file
    with open(CART_DOWNLOAD_DIR + "\\" + filename + ".p8.png","wb") as cd:
        cd.write(data)

def get_cart_listing(sub, start_index):
    # Search cart listings 32 at a time.
        print("Searching carts " + str(32*start_index) + " to " + str((32*start_index)+31) + "...")
        r = requests.get("https://www.lexaloffle.com/bbs/cpost_lister3.php?max=32&start_index=" + str(32*start_index) + "&cat=7&sub=" + str(sub) + "&version=000202cw&cfil=0")

            cart_info.append(cart_data)
    return cart_info

def download_cart(cart_info):
    dc = requests.get(DOWNLOAD_URL + cart_info[3])
    save_cart(cart_info, dc.content)

def main():
    # Make download directory for all the carts if it doesn't exist
    if not os.path.isdir(CART_DOWNLOAD_DIR):
        os.mkdir(CART_DOWNLOAD_DIR)
    for sub in [2,3,4,8]:
        print("Sub: " + str(sub))
        for p in range(0, PAGES):

            print("Waiting 2 secs...")
            time.sleep(2) # Trying not to kill the BBS
    print("Cart downloads complete.")
