I've attached an image I created of my control panel.
The outcome I was hoping to achieve is displayed below (as a mock up).
For example, say I'm playing Narc or NBA JAM (as displayed) in the example, it would show my panel and what does what.
My panel is laid out 3 over 3 as displayed.
From what I understood some of these panel viewers allow you to upload (or use an existing) your control panel image.
You then tell it what is what, so in my case button 1 thru 6.
It then knows what is what and will display the required controls for the selected ROM.
It's an amazing tool, obviously a huge help. Would certainly be a plus to not just myself, but any user of the cabinet.
However I'm loyal to MaLa, and I'd love a solution in MaLa.
To add, I'd love to display specific controls per ROM in Mame, but a general single mapping image per console emulator if it was possible also.
