Even the current version of MAME requires a good number of samples but Donkey Kong was fully emulated (no samples required) with version 0.116 and mame2014 is based off of version 0.159 so that's kind of interesting.

@caz That is fantastic. I love the panel graphics!

@ecks You are partially correct. I wasn't sure what you were talking about since audio seemed fine for me with mame2003. So I played a bit more until the plane boss. The audio is not unstable. It's not fully emulated. Slightly changed fps the further i went.

Mame2003: 60fps most of the time. Audio is not scratchy but not fully emulated.
Mame2010: Same as 2003.
Mame2016: 53-57fps and maybe lower, depends on the area. Audio is slightly scratchy when its in the low 50s but audio is properly emulated.
FBA: I tried it for the hell of it, I'm testing enough damn emulators. It did the worst..45-48fps but audio is properly emulated.

@mediamogul thanks.

I had firefox LD working with lr-mame 2016. The game is very slow but 100% working

Buzz, you were right mate. Lowered the clock speed from 1400 to 1200 and lr-mame2014 installed. Trying 2016 now as well, not expecting any issue.
I didn't have any issues running games at 1400, but it must have been a bit to high to be perfectly stable for compilation.

Thanks again mate.

@Melvin.FoX i will. And if i still have issues i will post them.
