oh, I thought you might have figured some way to get one of the cpanel displayers to show there while in mamewah.
  Hmm. I don't think it would be all that hard, to be honest.  The process would be exactly the same as how I get the category for the currently selected game on there:  You just batch-create them all beforehand!  The only tool that I know of that will save the image is 
CPMaker (I'm not sure 
CPViewer/CPVW or Johnny5 actually save the images) so you'll have to set that up first (it's hard though, I haven't even gotten all the way though setting it up!).
  Once you're all the way through that, you can either use ListGen and make a batch file to make all the images. You'll run the batch file, add your new artwork path to your emulator config in MAMEWAH, and finally add the new Artwork # to your layout.
  I could easily add this into MAMEWAH Config, just like I did with the category images.  I don't want to replicate what's already been done, so I will probably still have to require CPMaker/CPViewer/CPVW to be set up and working first.
  The tiny downside is that every time you want to update your controls.dat you'll have to re-run your batch file.  Not a big deal though.
  I sent a note to jcrouse about his CPViewer program since that seems to be the most popular and easiest to set up but I haven't heard back from him. Once I do and get a chance to try it, I can post specific instructions.
