What operating system are you using?
What emulator are you using for colecovision?
Adding a new emulator is simple..
in the configuration menu (press the tab key) go to the top where it says emulators. Go to eh bottom where is says add emulator..press enter..give it a name press enter. Now the set up is the same as all your other emulators..
(FB911 I'm sure you have done this..I put that there for future reference..)
be aware that most coleco vision emulators need a bios (that includes retroarch I beleive).
