v.s. cable no workie

Has anyone linked up F355, Voot, Dytona or any other DC games that are supposed to support the VS CABLE ?

I got it ( Dragoncast ) and it does not work

- is there a special procedure ?

- is my cable cable busted ?

- do i need real copies ?
Not yet.

Have you tried GameFAQs? Here's VOOT, for example.
