It seems the internet has noticed my site is a mess. My apologies for not having things in working order yet. MAME downloads are still available in the messy https://sdlmame.lngn.net/stable/ folder, or can always be found on my github here: https://github.com/mac-a-r0ni/mame/releases.
Site will be in working order in a few days!
I don’t get it. There is no dmg file in the zip. How am I supposed to run this thing?
Why would I put an archive IN an archive? The application needs the Terminal app like the site says, if you don’t know how to use it, I can’t advise in a comment online. It’s simple, but I don’t have time to teach you the basics of the Unix OS MacOS is built in top of. Look for videos on YouTube or twitch. Please educate yourself.
