Cartridge tilting is like wobbling a box of toys to try and make something work better. In video games, it means moving the game cartridge while it's still inside the console. This can sometimes make the game do weird things or show hidden features that you wouldn't normally see. It's like if you shook a snow globe and saw things that weren't visible before. But be careful! Cartridge tilting can also make the game crash or stop working, so it's not always a good idea to do it.
