This hack is working almost perfectly in vb 3.8.4
Little issue: It never showes RPG menu at navbar... yeah, that's all I found testing this hack.
I think you can make your own menu right?.
If you go to http://www.mysite.com/FORUM_PATH/rpgmanua.php you'll be able to see all needed links to make your menu.
I hope this info would be useful for you.
