Hey I'm running fw m-33 3.90 and I am haveing a problem running a game from iso/cso. i keep getting the message "The game could not be started. (80020148). I thought it might just be a bad ISO as the one other CSO i have still works. however after trying multiple rips of the game I have come here hopping someone has had the same problem and knows how to fix it.

P.S. I have gotten the 1.50 kernal update for my firmware.

any help would be appreciated.

Thanks!

Thanks for the reply. Sadly that didn't work. it may be possible that I've just got a bunch of bad rips. Any other tips you could provide would be much appreciated though.

My opinion is never to go to 3.90 m33. Lots of people complain it doesn't work.

Where can I find a (safe?) down-grader?
And how far should I down-grade?
