I am currently using the latest emulator MAME to run the Philips CDI system games (From what I understood MESS and MAME became one emulator). I have a few games on my pc with various extensions Philips CDI systems: .bin (.cue) .ccd .cdi I realized that only games with .cue extension are started correctly by the MAME emulator. I have a game I'm trying to play "The Apprentice", but it has .ccd extension. I researched on the internet and saw people playing this game in the same emulator I have. Every time I try to run a game with a different extension .cue MAME crashes and stops working. Can anyone tell me what I can do to solve this problem? CDI.ini GameEx.ini
