I used to be able to backup my games flawlessly on my older XP SP3 machine. I havent backed one up in nearly a year, so I had to refresh myself on the techniques. Ive not got a Kreon drive. Im using the hotswap method which used to work great! Setup: Modded 360 to play burnt games Optiarc DVD RW AD-7240S ATA DVD Burner Samsung CDRW/DVD SM-332B ATA hotswap drive (disassembled) abgx360 GUI Version 1.0.6 Entire Video ISO Archive (Waves 1-13 from the abgx360 website) >> Question: Am I supposed to copy these to the %APPDATA%\abgx360\StealthFiles folder or the Program Files (x86)\abgx360\StealthFiles folder? Ive put them in both to make sure... Games ripped using wxRipper 188.8.131.52 (Ripped original copies. No downloads.) DVD used for hotswap: The DaVinci Code (Full Screen - Disc One ~ 7.7gigs) Size of .iso: 7,651,848 KB Current Game: Call of Duty Modern Warfare abgx360 Settings: Options: Check/Create .dvd file Check Stealth Verify if Stealth passes Use colors Verbosity: Medium Check for AnyDVD style game data corruption Check for updates Check Game Partition CRC when needed AutoFix: Threshold: Level 2 Trust SSv2 Angles Adjust SS v1 angle 359 for iXtreme < v1.4 Fix C/R Table if data is invalid Adjust angles that deviate more than 3 degrees from their CCRT targets Misc: Region Code: 000000FF Language: English SplitVid: Add if it doesn't exist or isn't valid (I'm not sure what this should be) Images: Extract images when using HTML output abgx360 Results: Everything checks out... Except at the very end I get "Game partition CRC does not match the verified ini!" Why am I getting "Game partition CRC does not match the verified ini!"? I don't just get it for Modern Warfare, I've tried Crysis 2, Red Dead Redemption, Modern Warfare 3, and more. NOTE: I don't plan on putting the modified xbox online. Do I even need to run abgx360? Is there someway to verify the .iso will work before I burn it and possibly waste a disc? EDIT: I decided it's worth a disc to figure out the problem... I think The DaVinci Code isn't large enough. Does anybody know if that could cause the error I'm getting? If so, is there a list of DVD's or a recommended size to use? I figured this disc would be large enough. I used to use The Dark Knight, but I no longer have it. Any help with this problem would be much appreciated!
