Just a heads up for anyone using the C64 Official pack on Win7 64bit. The cmd.exe file in the Emulators Official\Pipmick Official\Commodore 64\BAT FILES directory will not run and throws an error. I copied the system one in its place and all good. The symptom I was having was that no C64 game would launch from within CoinOPs. It would go to a blank screen for a second and then back to CoinOPs C64 menu without any error.
Thank you very much to everyone involved in putting this awesome thang together. It's awesome, oh did I say that already.... Cheers
