Thanks for the reply. I was more for my brother (i have no issue with command line GM

), is there a frontend about that looks and acts more or less like the standard UI found in MameUI at all then?
I have tried MameUIFX, but i notice slight audio skipping and a constant sync tear on screen when using 'Prescale 3' option. (rolling thuder being a game i can think off the top of my head) not sure if its the program at issue or the PC his using (but GM has no such issues)
