Okay, I did some re-testing on my issue and tried to use three different extraction programs. I think the fact that I keep trying to use Modio 3.0 instead of other, newer program is what my original complaint is about, but I'll explain my woes with each program. Maybe someone can help me with atleast ONE of these issues and I can edit my NHL 2015 saves in peace.
I guess I should first mention, this is on XBox 360. I should also mention that I had ZERO issues editting NHL 2014 games at all. While I'm doing more mentioning, I *AM* trying all of these methods while running the programs "As an administrator".
Horizon - I can now successfully extract the file (in this current case, the file is named ROSTER 20150405142514). I open up the NHL DB Patcher, and successfully convert the file into a new file called ROSTER1 DB that I can open & edit in the EA DB Editor. I save my changes, and can successfully re-path\convert my ROSTER1 DB file back into ROSTER 20150405142514. I check to make sure that the file size is correct when I insert the new file (2.24 MB in this case, file size never changes), and I hit the "Save, Rehash & Resign" tab, which then displays a message that it was successful. When I close the file tab, the Device Explorer now displays a file size of 4.42 MB, which makes the save corrupt. Even when I re-open the file through the Device Explorer & re-check the file size of the actual ROSTER 20150405142514 file, it correctly displays the file size as 2.24 MB. This problem drove me nuts, and away from Horizon when trying to edit NHL 15.
Modio 5.25 - When I try to open any NHL 15 save in Modio, a screen with a giant red X appears under the "General" tab with the error message "Invalid Game ID". If I hit "Continue" to progress through the error message, I can still "Edit Package Contents" under the Advanced tab & extract the file from the save successfully. I can also convert, edit, and re-convert the file using the same method as I described above with using Horizon. I can also supposedly re-insert the new, editted file back into the package contents. The only problem is, the only way I've ever been able to save any changes to the USB was under the General tab at the bottom where it should say "Save to E0000041D841455C on USB Stick". That button isn't there under the General tab when I try to open a save for NHL 2015. It just has a box with a big red X. This problem drives me nuts. I've also tried various "backdoor" methods of saving to the USB stick, but the file either ends up corrupt when I look at it on my USB stick, or the edits never actually save to the file when I copy the files back onto my hard drive & open the supposedly editted roster file.
Modio 3.0 - For some reason, the NHL DB Patcher won't convert the ROSTER 20150405142514 file correctly when extracted through Modio 3.0. The file size listed in the Device Explorer correctly displays the 2.24 MB file size when I extract the file. When the file is extracted through Modio 3.0, the NHL DB Patcher does not correctly extract the file. I've even tried successfully extracting the file through Modio 5.25, doing my converting\editting\re-converting the ROSTER 20150405142514 file, and inserting that file into the Device Explorer, but the file size only shows up as 2.15 MB.
I'm basically about to give up. Lol. If anyone has an idea on why NHL 2015 is basically the same exact game as NHL 2014, but giving me 1,000,000 more problems editting roster & GM files, please let me know? Thank you.
