In almost every thread, someone always asks for a tutorial. So, here's a link to with them at xbox-scene.com
http://www.xbox-scene.com/tutorials.php
Try going to that site before asking where to get a tutorial. It's a great site with the best guides I've ever seen.
If it's a tutorial on evolutionX, you could go to the site I mentioned above, or also go to the official site at
http://evox.xboxhackz.net/ . They have tutorials specifically dealing with evoX, also has a FAQ on it.
Hope this helps some of you.
