I think you guys might've made a mistake on Virtual Halide, because I can't find anything about it. Are you sure it's not Virtual Hydlide?
Sega Saturn games are just named as the scene released it. Whether that's correct or not I cannot say.
A quick search over at GameFAQs' Sega Saturn games list, specifically under "V"... http://www.gamefaqs.com/saturn/list-v ...indeed does not produce any listings for "Virtual Halide" so as seph mentions, the guys who did release this game in ISO format (I'm not entirely sure if it's in ISO format though & I just assumed it to be so as the game was originally in disc media) might have mislabeled it by mistake.
