The title is self explanatory. I have a game that I completed legit, and it has a 1000G Prince of Persia: The forgotten Sands. What is the file in the Xbox ? there are the these files Autosave Autosave Backup
If it's gamescore then you can't because gamescore is on the profile itself, but to get the gamesave onto here, you need to extract the file from a usb or hdd, which is you xbox, but you'll need a transfer cable for that.for extracting you could either use modio, uxbxplorer or any others that allow you to extract, you will then need to click on downloads on this site. Once this has taken you to that page, there is a button which says upload files, it is on the right hand side, just above any posts. then just follow the steps it tell you to do.
