ludo VS gamer-os

A similar project is Ludo [1] which is part of the libretro family. More for emulation but really a clean UI (it actually has screenshots)

Linux Mint is fine. You'll want to modify it to start using something lighter than Cinnamon (I suggest OpenBox); 4GB of RAM means that KDE and GNOME/Cinnamon are not going to be fun, and as you're using it for arcade games, you don't need much more than a launcher for Steam/RetroArch/EmulationStation/Ludo/Lutris/etc.

Have a look at https://ludo.libretro.com/ if you can't work out RA.

Ludo is better than both.

MULTI EMULATORS (basically one program that handles a bunch of consoles) I would advise you to avoid frontend or multi emulators like mame or retroarch, because they could be intimidating if you start in this area to start with a frontend multi emulator, I recommend this one witch is beginner friendly and have a good documentation ludo emulator

There's a spin-off of Retroarch that I think is way better called Ludo. It's basically a less confusing version of Retroarch with a really clean UI!

did you try retroarch? if you want something simpler, give ludo a try. It's from the same team, but made simpler. https://ludo.libretro.com/

I highly recommend Ludo, it's like Retroarch but much easier to use and automatically chooses the best emulator for each system. Just put in your roms folder and it'll automatically split them by console, then just choose and play.

You just want Ludo. Go use it.

This GitHub issue also appears to document something similar.

"Includes out-of-the-box support for Epic Games Store and GOG"

Vanilla Ubuntu isn't going to offer you that level of integration.
