This is great news - thanks Hiub1 and Minwah!
I'm already using game specific INI files to set resolution an otehr attributes like triplebuffering; so the million dollar question is, what would a game specific INI file look like if I wanted to use a different version of MAME for a particular game? And, are we talking about a MAMEWAH a MAME INI files?
As I mentioned, I'm running MAMEWAH 1.51, so I'll give it a try on this version (keeping my fingers crossed).
Cheers,
Breaker.
