Actually no black magic is being used, but how cool would it be if CD Projekt Red and port devs Saber Interactive pulled off some David Lo Pan shit and fit a massive action RPG like The Witcher 3 on a tiny Switch cart?
As a Switch owner myself, I kind of expect to have to download a massive patch to make a title playable after buy a physical copy of a game. It’s one of the reasons why I said, “fuck it” and bought large SD card and just downloaded all my games like I do on Xbox One and PS4.
However, turns out that the patches are necessary because publishers are cheap bastards. SURPRISE!
To get back on point, for The Witcher III, CD Projekt Red and Saber Interactive are putting the game on 32GB cart instead of the more standard, and cheaper 16GB card
I’m sure some fancy compression tech is being used, so who knows, maybe some cool black magic is being used?
