How to install mGBA emulator?

Excuse me,everyone,how to install mGBA emulator on the uConsole CM4?

It’s Debian-based, so apt-cache search mgba should help, and then apt-get install the package you want.

It comes with RetroArch preinstalled, though, and I think it includes mGBA. If not, apt-get install retroarch libretro-mgba should install it.

Thank you very much!
