@kaia@brotka.st the "memory card" slot was on the controller, which had a tiny LCD that would display logos, animations or even add extra functionality to the game (silly things like a scope in FPS games)
it could be used on its own like a tamagotchi to farm money or exp through minigames that you could download from the game disc!
however, yeah, it was an LCD B&W screen, kind of like the OG game boy, that one is a mod
@kaia Channels like Kurzgesagt make more money from selling merch than from ads. You're good with stable diffusion, so it could be a long term opportunity.
Another source is sponsorship. A choice between shilling a VPN service, some investment thing like Masterworks, or physical products like headphones and makeup products.
If you're going with just ads, it's better to have content about finance or AI cause those will have the highest CPI.
