I prefer to play games in their original aspect ratio, which for the old NEOGEO games is 4:3, but I've had a couple people ask me about playing ports of these games in a widescreen format, so I thought I'd make a quick video showing that you can do that in the "ACA NEOGEO" versions on PS4--here I show how to do it with ACA NEOGEO The King of Fighters '98 (because you can't do it with The King of Fighters '98 Ultimate Match, a bare-bones port of the PS2 version that did not add modern console options).
You can't quite stretch ACA NEOGEO KOF '98 to the full 16:9 width, but you can get pretty close using the "Size of the display" and "Display wider screen" Display Settings in the in-game Options menu (touchpad to pull this up, I think it was).
