I'm kinda a nub. I have 5.00 M33-6, and I think I need 5.5 to play Dissidia.

Now, I KNOW that the M33 version hasn't come out yet for the 5.5 FW.

Is there anyway to trick the psp into letting me play Dissidia?

Thanks for the help guys. I used the search button. I either didn't search using the right keywords, or no info about this.
