Yep....the search option is broken...but I can't fix it myself ...Have to contact Lev (owner of ztnet) to fix it.

Now to the sourcecode question:
I doubt I will release the sourcecode of the current ClrMamePro. It's became very very ugly over the last 5-7 years and uses Microsoft specific libraries a lot. It'll be a real pain to port it.
...but there might come something else in the future...time will tell.
