All right, I think I've got my rosters as "done" as they're going to be. I did add/update some rookies who made their NHL roster. I created two players who weren't in the game at all (Tarasenko and Cervenka). And I was able to use a roster trick to be able to move some of the Junior players who were in the game (Yukapov, Dumba, Galchenyuk, Grigorenko), but were underage, and therefore, not eligible to be traded to any team outside of the CHL. Then, I updated stats on a few prospects who were able to be moved to their NHL club (Kreider, Scheifele, Rakell, Huberdeau, Granlund, Hamilton, Silfverberg, Brunner, Schwartz, Kincaid) using a roster edit site that I found.
I moved the save to a thumb drive, and I'm going to just compress the entire "Xbox 360" folder that shows up on the drive (the NHL roster save is the only thing on it...but of course Microsoft has to put all their system files and proprietary shit on there) into a .rar file so it won't take so long to upload/download.
I'm hoping that if you guys move it to a blank thumb drive, your 360 will recognize the file, and then you can just assign it to your gamertag like I was talking about last night. If that doesn't work, there are "other methods" that can be used to import a save. They're just a bit more involved. Anyway, as soon as this finishes compressing and I get it uploaded, I'll post a link. Then I can actually go back to playing NHL 12 again, haha.
