Paul said that he is using a Grip controller with the Multiport connected to his system, so maybe that's whats working for him. If you have anymore tips, please send them to me!
Other than the bloodlust emu's, there is no know emus that directly support GrIP.
That's true, every windows 95 emulators should support GrIp by way of DirectX's DirectInput! If an emu doesn't work with directX, just use the GrIP software or SnesKey9x for windows...
