Not that I recall. About 2 years ago someone said they were able to compile it for Linux. Have you tried?

I've never used anything by Apple, there's no support for them. Also, I've never used Unix/Linux in any of its forms. 100% not interested either. So, can't help you with that, at all.

If it's happening with MAME then you'd have to ask the developers. That having been said, I asked one of them to check and they said there was nothing wrong. However if you made the savestate with 0.279 and then you're trying to load it into 0.280, then they have no support for using a savestate between versions. In that case then it's just bad luck.

What happens with standard MAME 0.280 ?

MAMEUI64 0.280.0 has been released. Available at https://messui.1emulation.com References to "SW Files" have been changed to "Loose SW", which is the more commonly known name.

I don't have a joystick or controller, so the functionality has never been tested. I don't know what the numbers mean either. But maybe someone else here knows more.

No. Any version of MAME can produce a dump. A debug build switches on various internal checks, such as "assert".

Most people don't need it. See: Basically, if it crashes you can get symbols (where it crashed) instead of numbers in the crash dump.
