I think it best to use the standard configuration format for the emulator. You will see the editor very quickly, minor eyesore, but all will run smoothly.
First, set it up as directed in the tutorial/how you have VP8 set up (if you do).
Second, use
this 'cabinet' vpinmame dll. Rename the original in your folder to something else (for example, vpinmameo.dll), and rename the cab dll to vpinmame. Remember to reinstall it and reset your vpinmame paths.
Three, get and put closemul in your main VP directory, and point the exe path in Mala to that. (No need to click on closemul or anything. It knows what to do all by itself.)
Should be smooth as silk. (I should be this in the tutorial!)
