Thanks Haze for an explanation into what needs to be done. Mame will get there in the end.
As we are on sega chips Wonder Boy to me seems to not sync right when playing the game so is this 1 of the things that decapping the Virtual Fighter & Star Wars would help or is it just my laptop not fast enough or have i got the settings wrong in Mame ? My laptop though is an intel i5 with 6gb of ram so should be fast enough.
