Not to my knowledge. I've always had a green light up until this latest release of ClrMame. Wasn't sure if it was ClrMame or MAME32 being the culprit. Even with the newest release of both (3.103a for ClrMame, 118u2 for MAME32) I am still getting a red light even though it's showing me I am missing nothing.
