In preparation for Dovahfest*, I was trying to take his save file and move it to a new account so we could play simultaneously. I set everything up (took over his gamertag since I earned most of the 16,000 gamerscore, got his old gamertag on a new live account, etc.) before learning that saves are owned by accounts, and I couldn't play the old save on the new account.
I went looking for an answer on Youtube, and it told me that it could be done with a program called Modio, a USB flash drive 1gb or bigger, and a spare save file. Here's how I did it:
- Copied the save I wanted to move from the old account "x100tacks" to a 1gb flash drive. (the 360 will prompt you to format the drive before you use it.)
- Created a new save for Skyrim on the new account "Northsided" on the same 1gb flash drive.
- Used Modio to do the following:
- Open both saves in two separate tabs
- Paste the profile ID from the new account save to the old account save
- Save the old account save to the new account save folder
- Re-insert the flash drive in the Xbox and check that the old save now shows the new account name
- Copy the file I modified to the hard drive and loaded the game.
- Celebrated my victory.
