Im trying to compile some sort of information page on the gravis GriP multiport and compatible software. Obviously all windows games that support directinput work fine, but there's also a number of DOS games out there with native support for the multiport and/or gamepad Pro in GriP mode. If you know any, or run into support in the readme files or other documentation let me know.

So far:

X-Men Children of the Atom 2-player support.
Nesticle 2-player support. (4 player test pending)
Tripe Play 97 4-player support.
Advance Mame Dos 4-player support.
