Bought an old Xbox

[lowball]

Plug the controller with memory card into the PC. Now start the Action Replay Software. Does it list a memory card in the left pane?

If so, I went ahead and uploaded the PAL game save to mediafire, you can find it zipped HERE.
Go ahead and download, navigate to download directory, then extract all the files inside that zip.


Now you will notice SC Save 1 & SC Save 2. You will need both of these.
Inside the first folder (SC Save 1) there is a zipped udata file. Don't unzip - Drag and drop that into the center of the Action Replay software (where it shows all the games). Do the same thing for the second udata file (SC Save 2).

Now inside the Action Replay Software you can navigate to Splinter Cell and you will notice a new save titled "Linux Profile".
Drag and drop that to the Memory Card in the left pane of the action replay software.
Up top there is also a new "Game" titled Linux Installer, drop that onto the memory card as well.

Once that is complete boot up your xbox with no game in the drive. Navigate to the memory card and copy those saves to your xbox hard drive. Now when you pop in the Splinter Cell disk and attempt to load a checkpoint you will notice a save titled LINUX (or something like that)

Let me know if you're still stuck.
