Ok good news that is works for digital version of the game, albeit after a fricken 15gb overnight download
So my status is last night, I backed up my 1.01 save and delete the game, and set it to download. Was complete when I woke this morning, so removed the LAN cable and set it to install. Then it was time for work 7 hours to go
What's the quickest way for Digital users to exploit the glitch?
1. Use the Backup Utility in system menu to Backup with 1.01 installed.
2. Backup v1.01 game save
3. Delete the game and download digital version (1.00) and install.
4. Start game skip patch, sell vision car, buys cars, save.
5. Backup v1.00 game save
6. Use the Backup Utility in system menu to Backup with 1.00 installed.
7. Use The Restore Utility in system menu to Restore previous 1.01 backup.
8. Start game, buy vision car, save.
9. Use The Restore Utility in system menu to Restore previous 1.00 backup.
10. Start game skip patch, sell vision car, buys cars, save.
Rinse & repeat steps 7 -10?
