It's really a matter of convenience (and doing something during lock-down) that I wanted to load my emulators on the pinball. I just ended up making a controller for my make-shift pinball machine and thought it would be double fun (and save on space) to include pinball/arcade in the same cabinet. I've been testing out more with GameEx EVO and it's really more a matter of getting the individual emulators positioned where I want. Most stick where I place them, while others jump to full screen. Just need to look through each emulators config/arguments and adjust accordingly. FINALLY got Daphne working and figured out CLRMAMEPRO over all this so very well worth the time
I'll check out the article, thanks for sharing and here's a pic of my current Franken-PinArcade machine for reference lol
