it was kinda silly of me.
originally I had posted.
having trouble getting mamewah to generate the new list after changing the folder contents.
I had updated the folder contents and went to re-generate the list but instead of it generating a new list it kept showing only what was in the folder prior.
I then found out it was becuase the roms extension path names differed in the config folder for those particular emu's and after I changed that it all worked again like it should have and generated the list correctly.
