I can confirm that they do. Its the only way i have of playing my VC games, seeing as how i dont have a classic controller or GC controller ( i actually sold my only gamecube controller when i bought my GC, and bought 4 PS2 to GC converters, i hated the GC controller that much, was not designed with someone with huge hands in mind, but i digress). Keep in mind that it only works with stuff that supports the GC controller, so some stuff that has classic controller support but no GC controller support ( Geometry Wars Galaxies comes to mind) will be unplayable with the converter. Im assuming since this is a classic controller knock-off, that it wont have those problems. Also, id like to add that i prefered the Dual Shock d-pad over every other controllers d-pad, with the exception of the snes.
