Having copied the contents of the GTC disc to my Hard drive, in preparation for burning a DVD-R copy, I noticed a file called "system.cnf" that's a 54 byte file. I surmised from the file's name that it's a "system confirm" file, which would be the actual file that's read to verify your system, and engage the regional lockout etc. So, I was going to try burning a copy of the game without that file on it and see what happens. What I don't know is if it requires that file to even start up...But with any luck I will have removed the problem...I'll let you know how it turns out...
