MacMAME, and getting Galaga to work. Why is this hard?

[MacMAME, and getting Galaga to work. Why is this hard?]

The roms on theoldcomputer worked! Yes! I didn't find that site in my previous searches. So since I can finally play all the games I want, I am gonna just keep my MacMAME. I guess I don't know what to tell you about QMC2 not working for me. I had no idea what I was doing anyway. I tried to run it just so I could send you the error details but when I install it it doesn't seem to create any new thing for me to open. I searched it and the only thing that came up was the installer. Anyway, thanks everyone for helping me!

Ok, I think I downloaded the right things. I tried to run QMC2 but it won't open. It just crashes itself every time. What do I do with these things once I download them?

Ok so I have been scouring the internet trying to find an easy answer for how to get Galaga roms to work with the latest version of MacMAME. Or if it would work on an earlier one. I have found no real direction to go with this. People are talking about how they have fixed their roms with other programs but to a novice this is basically gibberish. So my question to the internet is, is there an easy guide to getting the missing files from the rom and making it work? Or more importantly, has someone who actually knew what they were doing fixed the roms and shared them and I am just not finding it? I am just perplexed. I have never not been able to find an answer for my novice emulator questions.
