Ridge Racer 7 recently got a 3D patch ("3D LicenseVersion" as they call it). At the moment, it's only available for Japan and Europe, but I did manage to download it from the EU PS Store. Sadly, it doesn't seem to be working on the US version of the game. All the 3D demos on PSN have easy-to-find menus to enable 3D, but this doesn't seem to do anything.
Any thoughts on this? It's a PS3 launch title getting an update, and not a very well-orchestrated one at that.
