Overview of LaunchBox Premium with Big Box

This program is a gaming frontend built initially for DOS. However, now it supports a slew of emulators and PC games for an all-in-one multimedia solution.

Whereas the likes of RetroPie, Batocera, Lakka, and Recalbox feature emulators built-in, it doesn’t. As such, you’ll need to add your own.

The difference between this program and Retroarch is that Retroarch provides emulators while offering a pretty user interface. Thus, it is used in conjunction with Retroarch.
