Ludo (libretro frontend) VS Happy Chick

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) [1]: https://ludo.libretro.com/#about. - Source: Hacker News / 9 months ago

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. Source: 11 months ago

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! Source: over 1 year ago

Happy-chick. Stay far, far away. Shady as all get out. Here for completion, but otherwise, you’ve been warned. Would not be surprised if it’s somehow sending your stuff to the east. (don’t do it.). Source: over 2 years ago
