Mac OS X10 How to use mGBA

[pwonnen]

Hi everyone,

I am new to this and would like to play some GBA games on my Mac. I dowloaded the OS X version and now I have a file named: "mGBA-0.5.1-osx.tar.xz" sitting on my desktop.
What am I missing?    I tried uncompressing it but it seems useless...
Thank you for your help!

What version of macOS are you using? It should decompress properly on 10.10 and newer, IIRC. If not, download The Unarchiver and open it with that.
