I've never seen or used Maximus Arcade, so I can't really comment on that. You can however put the appropriate settings in your mame.ini and launch MAME without MA being involved. MAME has it's own internal frontend now.
What I can confirm is the latest files found here work with the 4 or 5 frontends I have here on this machine as well as running MAME from command line.
I haven't run into any issues since I reported some minor reset issue.
My guess would be it's some issue with MA. When is the last time it got a new version and is it still actively developed?
Okay, NM, I found the above answer after clicking forums which take me to BYOAC with many threads about problems.
Perhaps consider looking into GameEX if you need a look similar to what you're used to. There tons of community created themes that look just like their youtube video.
