There was a very in-depth readme.txt file included with Devhook .46 when I downloaded it a while back. I would look for that b/c it helped me out.
I would encourage you to upgrade to the custom firmware versions so that you don't have to load devhook to play any games

You will have all the benefits of the higher firmware versions and still be able to play homebrew. We would need your current FW before we continue to recommend things though.
