@jamesb14 You really need to do a little more research to understand how the system works, read the documentation and see the tutorials:

Quickly answering your question:

First, see if your hardware supports these consoles (otherwise, it won't really appear to you):
https://recalbox.gitbook.io/documentation/hardware-compatibility/emulators-compatibility Second: The official Recalbox does not come with any copyrighted content, only those that have official authorization from the creators, so you need to add the ROMS and BIOS on your own, the systems will appear in EmulationStation only after you add the ROMs on the desired consoles.
