I have been waiting for these particular games to be running for years and years now....... as are a lot of people I think. I don't know anything about coding MAME, but from my understanding there is something about these Model 3 games that no one has been able to get working properly yet..... and it's not due to lack of people trying I don't think. When someone finally does figure it out, it's going to be a happy day as Star Wars Trilogy is my favourite arcade game of all time.
