Is there any all in one software solution for Windows which doesn't require you to look for stupid settings, various program versions, various roms for different games to work? Anything that takes care of everything and is very simple to run? Please suggest something if you have tried it only. I can use google myself too. I want your personal opinion/experience.
RetorArch is your best bet, but MAME support is flaky. That's really the only complaint I've got against it. I still prefer separate emulators though.
