I'll start with the question ... certain games aren't saving the high score. Donkey Kong (dkong) is one of them. I have checked that "hi" exists under my MAME directory and that it is referenced in the .ini file. Any ideas on how to correct this?
Now, my picture ... built this as a Christmas present for my kids:

It's roughly a LuSiD cabinet, but with a J-LO backside

The control panel is from Jakobud. Modified the depth of the CP cut in on the cabinet and the height to match Jakobud's design. It's modified enough ... we'll just call it the "dot cabinet."
