The game's DVD read function writes an invalid value to the entire read buffer. It then calls DVDReadAsync() and without waiting for the read to complete at all, it checks if the invalid value is still there. If it is, then the game fails. The check always passes on console because DVDReadAsync() -> issueCommand() calls DCInvalidateRange() (dcbi) on the read buffer, which reverts the invalid value writes. Refer {{Issue|10927}}. | The game's DVD read function writes an invalid value to the entire read buffer.
