Idk back on one of the dragonball ps2 games I remember they had little interactive loading screens and I figured out if I popped open the disk reader (the slim one had the flip up drive if I remember correctly) it'd let you stay on the loading screen "game" indefinitely, they even sometimes had fun recognition like by default it'd spawn green sibamen, after a point it'd change to spawning red, I don't see how you'd ever come across that in normal gameplay and because it never took that long to load in normally, but someone thought about it and added that little fun touch.

Anyway when I closes the disk reader the game would finish loading.
