And if you read what you linked here, it says: "Gran Turismo 5 ver1.00 PAYLOAD: some user here report to me that GT5 works better with PL3 3.55 than it does with V4B 3.55" In my case, NFS:HP has a eboot.bin for 3.41 and thus works without spoofing. However, GT5 asks for a system update and exits if you decline. So we need 3.50 spoofing. Probably it's enough to just download this unpack and replace the files in /opt/psfreedom/payloads/ on your N900 Could someone try that out? Busy with NFS right now.
