The PC port, while it features better graphics and a couple of other extras, automatically installs DirectX 5.0 when you go to play. It does this even if you are running a later version, and if the game starts up and doesn’t detect DirectX 5.0, it will install it for you again. There’s no way around this: every time you go back to “Enemy Zero” you will suffer this indignity which will require you to re-install a later version of DirectX every time you’re done playing. So just don’t do it. Ever. You will invest in a Saturn to experience “Enemy Zero” and forget that a PC version even exists."
