I have a modded xbox that can run games installed and copied from pc through a dvd disc, but somehow it doesn't have xex menu on it or dash lunch, even xell doesn't work, nothing happens when i boot the xbox with the cd tray button, and I've actually tried downloading xex menu on my pc and copying it through horizon, but when i plug it in my xbox it shows up as corrupted, I've also tried connecting my xbox HDD to my computer and tried putting xex menu there (by putting the code9999 folder in content>000....) along with a game that i've coverted to a "GOD" format, they both showed up as corrupted on the xbox.
