Gran Turismo PSP requires 6.00 Firmware

And here's another bad news for us PSP fans... Gran Turismo PSP requires firmware version 6.00. Yeah you've seen it right! What's more bad about it is that they say that this don't have career mode (what are you thinking now? ☺).

We hope that the 937 MB is only a demo and there will be a full version of this game that have career mode which very essential for every game...
