The best LaunchBox alternative is Playnite, which is both free and Open Source. Other great apps like LaunchBox are Lutris, RetroArch, Retrom and Lemuroid.
Excellent emulation in most of the systems I have run, simple/classic GUI, and it is updated regularly. It combines the ease and functionality of some of the classic standalone emulators into a multi emulator. LaunchBox is great, but for those looking for less frills, BizHawk is very good.
