Someone asked me to write a guide for this, so here it is. What is abgx360? It's a tool that checks Xbox 360 game ISOs. It can fix various issues with an ISO, including patching in missing stealth files and the topology data required for LT+ 3.0. It also has online functionality and can check an ISO against information held in a database of known good retail rips. The current version of abgx360 patches all AP2.5 games for use with LT+ 3.0, so please bear that in mind before using it as games patched for LT+ 3.0 are not compatible with earlier versions of LT+! Download and installation Download the program here: - http://www.abgx360.net/download.php Once you've installed the main program, download the video ISOs that are listed at the bottom of that page. If you download the self-extracting video ISOs, they will automatically be moved to the correct directory on extraction. If you download the standalone ISOs, you will have to extract them to the correct directory manually. To find your stealth files folder (where you need to place the video ISOs), fire up abgx360 and press Ctrl + F, then hit "Yes" and it will open the folder for you. The video ISOs are required if you have a 360 game ISO that has a missing, incorrect, or corrupt video partition. What is "stealth" and "verification"? Stealth - When an original game is ripped, certain information is ripped and stored in "stealth files" inside the ISO. This information is what makes you safe (as safe as you can be anyway) on Xbox Live and it's what stops your console being flagged for failing anti-piracy checks such as AP2.5. Verification - abgx360 works in conjunction with an online database. Trusted users rip retail discs and then upload the stealth files from their rips to the online database. When you use abgx360, if the game you're checking out is present in the online database, the stealth files are compared with the stealth files in the online database. If everything matches, your game is "verified". If it doesn't, then abgx360 will patch in the stealth files using the verified files from the online database (as long as you've set it up to do that). So it is vital that your ISO passes the stealth checks. As for verification, it depends. If you are ripping your own games and you know what you're doing, verification is not that important as you already know that your stealth files are good as you ripped the game yourself. Setting up abgx360 This setup guide is for people who want to make use of online verification to check and autofix ISOs. If you're ripping your own games and you absolutely trust your own rips, you may want to use different settings (more on that in the next section). Run through the various tabs in abgx360 and make sure that your settings look like this. You can ignore the QuickStart tab as nothing needs to be set there. Options tab: - Manually Patch or Extract Files tab: - AutoFix tab: - Rebuilding tab: - Misc tab: - On the Misc tab, press the "Select..." button to the right of "Your console's region code" and select the region code for your particular console, rather than just copying my setting. You don't have to set your console's region code at all, but if you do, abgx360 will warn you if a game you're checking out is from a region that won't play on your console, so it can save you wasting a disc and wondering why it won't boot. Once you've got everything set up, click File - Save Settings..., make sure it says "Default" without quotes in the save settings box, then hit OK. Your settings are now saved, so when you fire up the program in future, it's ready to be used. More on the AutoFix tab If you're ripping your own games and you don't want to have your own trusted stealth files patched by those that are in the online database, then you need to change the AutoFix Threshold on the AutoFix tab. Lower it to level 1 or 2 depending on what you want. Each level has a description of what it does, so you can work out which setting is best for you. Using the program to check an ISO 1. On the main program window, make sure that "File(s)" is selected from the Input drop-down list. 2. Click the little folder icon, upper-right and browse to your ISO and select it. 3. Hit the big Launch button at the bottom of the screen. Using the program to check a burned disc 1. On the main program window, make sure that "Burned DVD" is selected from the Input drop-down list. 2. Make sure your DVD is inserted into your drive, and select your drive from the drop-down list near the top of the program window. 3. Hit the big Launch button at the bottom of the screen. Obviously, abgx360 cannot autofix data that's on a burned disc. If your burned game fails the stealth/verification checks, you will need to rip it with ImgBurn (or your chosen program), run that ISO through abgx360 to patch it, then re-burn it. How to interpret the results Green = Good Yellow = Warning Red = Bad If you see all green, you're good to go. If you see any red, something is wrong. As for yellow, it really depends what the warning is about and whether abgx360 was able to autofix the problem. For instance, if a game is not present in the online database, then the ISO you're checking will fail verification simply because there are no stealth files for that game in the online database to compare with, and you'll see a warning about that in yellow. That doesn't necessarily mean that your rip is bad. It just means that it cannot be verified at this time. Use your own common sense to interpret the results, but if you get stuck, just ask. Post your log (or a screenshot of it) if you need to ask a question. Is there a list of verified games? Yes, there is a searchable database of verified games, HERE.
