Elgato wont work, as like I said you cant record through the HDMI slot, and the Colossus wont work because its not recording through HDMI.

Il repeat this. Final Fantasy A Realm Reborn must be displayed through HDMI, but the Ps3 will not record through HDMI because of how it is made.

Therefore I cannot think of any way it is possible.

If I am wrong please correct me.
