Seeing that you are running with an ArcadeVGA am I to assume that you are hooking this PC to a real arcade monitor??
If that's the case.. that too limits the front ends..
As far as I know, Dragon King is made for PC's running at really high resolutions (1024x768+) and frequencies that are outside what a regular arcade monitor can handle.
I've never tried 3Darcade.. not sure if it'll work on an arcade monitor.. so you're stuck with MAMEWAH under Windows XP..
there's lots of good info here on how to configure it, and how to hide the existance of Windows XP!
Good luck.
