I would think not. I imagine Sony would be very interested in a magic homebrew
application that could prevent a 1.50 from playing ISOs.
But like I said, it seems the problem is isolated, and I still don't believe it has anything
to do with X-Flash since all my stuff is working fine.
I could provide a video of this, including the debranded intro, etc. but the video file
would be quite large.
I will continue with updates, especialy since ppl are waiting to put the sound on their
intro screen back to normal. X-Flash V3 has a lovely warning screen at the beginning
