It's true that on a faster system, using OpenGL will make less difference.... but it will always be faster than any other method I reckon. With an overlay, you can't just write to the video memory and expect it to be the same speed as writing to main memory, certainly not if it's a pixel at a time! MAME would have to render to an off-screen texture anyway because of the amount of pixel operations.
Overlay is pretty much obsolete these days anyway as it's been replaced by render-to-texture methods... using OpenGL. Video cards are optimised these days for texture upload and rendering.
For the record, I have no problem with your porting MAME4All if you want to - just saying I don't have the time to do it. And personally, if I can play games like Ghouls n Ghosts without problem, then I'm happy - whatever version number it is. :)
