fairly simple question, is there a way that a cart can write data to disk to produce another cart? I ask because I am wanting to make a tamagotchi type thing to learn some of the more of the pico-8 API that i otherwise wouldn't,such as multi-cart projects, as well as making a menu, something I surprisingly haven't done before. (any tips on that would be appreciated 😅). my current idea is that you would have the main menu, a standalone cart. it's sole job would be to create and load another cart, that being the main tamagotchi cart. each pet would have its own cart, that could be loaded by just skipping the main menu and loading the cart. my current issue is that I don't know how a cart would create another, or even if that's a possibility. another option would be to have a template cart that then maybe gets loaded with arguments, allowing for customisation that way?
