If you are using the version contained in that .rar file, the community highly recommends several patches to make it playable on modern systems:
: You can play through the entire game as Dante’s twin brother, Vergil, who uses a unique "Dark Slayer" fighting style with his signature weapons: Yamato, Beowulf, and Force Edge.
: A new continue system that allows you to restart from checkpoints indefinitely. This is much more forgiving than the original "Yellow Mode," which required a consumable item to restart from a checkpoint.
