I have a strange problem with Sonic All Star Racing. I have cios38 rev 17 & Neogamma r9 installed and it lets me load up the game fine. However after choosing a racer and track it starts to load and then I get "Disc Error Disc cannot be read. Refer to operations manual" I have burned a couple of copies and they all stop at the same point, load the game fine but then error when loading the race Is there a certain ios i need to have installed ? Thanks for any feedback as my son is driving me demented to get this working.
