Its fully operational if you configure it to run without Trinity. You need to do the following:
1) Use Belphegor as combat routine.
2) Use a custom item rule xml file to pick items.
3) Use RadsAtom to manage profile deaths.
4) Use Unstucker to manage stucks.
If your character is a melee class, Belph runs very well. In my case (I use a DH), Trinity's combat is better.
