Something I had been working on a while ago, this script allows you to attach the MHS debugger to a game protected by xlive as well as use auto-hack on it. Open up the script and edit the location of disx.dll , compile and add. Configure MHS so that is uses software breakpoints for auto-hack through the options.
This will work on 32-bit versions of windows as long as the game is protected by xlive alone , it could also disable separate protections the game itself (not its launcher) has but its not guaranteed.
Credits go to Psych for his method of patching xlive's memory checks, thanks to L.Spiro for helping with the script itself and for MHS.
