That video proves nothing. I can do exactly like he has and it will be fake. There is no proof the game ran. All he did was show you the first menu. I want to see the game run after a full reboot to prove there is nothing loaded from a backup loader first.
How about show us Portal 2 running. That'll prove a 3.6x game will work. Try a game that doesn't work instead a game that's already got patches.
oh dear i hope that this is just the tip as this shows nothing new. i hope the statements of 3.6x+ games booting will come true or this is gonna be the biggest let-down of all times ( just another useless cfw ) first the removal of psn and now a vid showing old abilities... time will tell.
