WARNING!!: Play this save offline the first time you use it. The reason is that all the chapter achievements will pop at the same time after you complete any level.
Modio won't work with this save. You have to use Horizon and change the Profile, Console & Device ID's to match yours, then rehash and resign...
This save is for the US version. Try this for EU version. Put my save into Horizon click on the contents tab and extract the "NA_00000000.000" file to your PC. Then create your own save on your Xbox and then put it in Horizon. Click on the content tab of your save then right click on the "NA_00000000.000" file and replace it with my "NA_00000000.000"file. Then Rehash/Resign and put it back on your 360. Hopefully that will work.
For the MGS2 & MGS3 saves that I downloaded I simply renamed the EU saves with the name of my US save and that worked. You can try that if the note above doesn't work.
