So is it settled, everyone will stop fighting if it gets an About Coinops option where you can see credits and so on? The idea of having the emulator used after each game is going overboard but an About Coinops is a nice idea and those who care will use it, most won't but at least it's there if people want to know who did what.
I agree, an about box is fine, listing it after each and every game is crazy. Credit where credit is due but not going overboard. Usually a readme is enough as in the end most people don't care who did what, they just want to use it.
