VCD does not have to be recognized by system in order to play it. Frogger used his own routines to directly access CD, so all you have to do is use VCD as file name, and specify correct CDUNIT and CDDEVICE (and as those two are saved in prefs file, its not needed to type lot of crap in CLI Mr. Thargan

Do it once, insert VCD into drive, start frogger from an icon, and press V. voila.
