For now I was looking at building a library from MAME 2003-Plus, MAME 2010 and FBNeo. I'm still trying to wrap my head around ClrmamePro.

I've been reading the docs, I understand that the version is really important, CHD and samples. I've been looking at trying my hand at Arcade hemulation. I've been exploring more and more features and I hope I'll be able to help more rather then asking questions.
