I just use the latest versions of OM and OMEGU. I don't use RSRDC with OM - I only use it for my US install. I could be wrong and Lurker will certainly straighten us both out, but you'll be much better off asking on the SH4 UBM Mods board.

This link is to the actual OM thread. You don't need to read all 78 pages. Just ask and you'll get all the help you can stand.
