These problems and solutions are only applicable to version 1.6 and 1.6b Xboxes.
Version 1.6 and 1.6b Xboxes have an Xcalibur video encoder, which has trouble displaying some games in 480p. The games will either show a scrambled screen or fail to boot altogether. Installation of a MakeMHz XboxHD+ provides a blanket fix, but for an alternative software-based solution, some of these games can be patched using JCRocky5's Game Loaders script.
Patching Games
- If you are running XBMC4Gamers, you can skip downloading the script, as it’s built into gamers. ( Settings > Skin Settings > Scripts )
- You will need XBMC or XBMC-Emustation set as your dashboard or launched as an app.
- Download JCRocky5's Game Loaders script for XBMC or XBMC-Emustation.
- With XBMC open, copy the "scripts" folder into the Q partition to merge it into your current scripts folder.
- Navigate to the Scripts section of the dashboard and launch "480p Game Loaders". It will do an initial setup, then choose "auto install" to have it scan your hard drive and patch any games that need patching.
- Manual install mode will allow you to individually select the game you want to patch.
- Alternatively, you can run the "default.py" file to launch it from any variant of XBMC v3.5.3 onwards.
