Ok basically I have opwolf.zip. I try to load it and it says I need b20-20.29
I search for that file. I find that the files inside my opwolf.zip do not even closely match the files that are supposed to be in there.
This is what is in my opwolf.zip:
opwlf.13
opwlf.29
opwlf.30
opwlf.39
opwlf.40
opwlf.72
opwlfb.09
opwlf_s.10
opwlf_s.21
This is what I found is supposed to be in there:
b20-03-02.30 
b20-04.39 
b20-05-02.40  
b20-20.29  
b20-07.10  
b20-13.13  
b20-14.72  
b20-08.21 
Now admitedly I am a NOVICE when it comes to ROMS, parent ROMS, and that stuff. I dont know how to use clrmamepro (I know I need to learn). My ROM set is supposed to be complete and clrmamepro verified.
Does anyone have any idea why the files are so diffrent?
THX!
