Being a noob to LaunchBox, I have tried querying my problem and can’t find it, so if someone could direct me please. Here is the problem, when I start LaunchBox, and as an example I start Centipede, and get ver4. which does not work on my cocktail MAME. I need ver3, but when I right click on the game the drop down shows ver3 but only in my MAMEUI64 front end. So when I start it it starts my MAMEUI64 front end.
How do I locate the ver3 roms in LaunchBox, and assign it, as the one to open, in LaunchBox?
