Is there a way to transfer a save file from X360 but of an original xbox game to the newer...

Unfortunately original Xbox saves cannot be transferred to the newer systems.

With the Transfer Cable, you get the option to Move an original XBOX save file to another HDD.



USB MUs cannot store original XBOX save game files.

Each save file is tied to a profile and it cannot be recovered without the original profile present.



The original Diablo 3 and Reaper of Souls are two different games. The save files are incompatible without transferring the data within the game (transfer from Diablo 3 into ROS).



However, the process is not reversible (i.e. you cannot transfer characters from ROS into Diablo 3).



Therefore, unless you still have the original Diablo 3 disk, your save will not be usable.



Sorry.

No. The only way to move an original XBOX save game is from the Transfer Cable direct to another HDD.

The old file transfer software did it, but it moved EVERYTHING and erased the old drive afterward.

There's no other supported way to move original XBOX saves.
