If you want to know how, then here.
1. Unpacked and decrypted the GT5 and GT6 files.
2. Moved over the TGTT files from GT5 to GT6.
3. Modified the database to include the track in GT6.
4. Modified the btree to include the new files (not so easy task, took me a week to code tool for this).
5. Encrypted and packed the new files.
6. Moved them over to my PS3.
7. Played the TGTT.
From RazerMan's YT channel.
Would be nice if RazerMan could give us one last GT6 gift and make a patch (if possible) to include the track and missing Ferrari F1 cars
