Not only that , but i downloaded the source code and i looked in it with a friend of mine, and the actual network/sync part is missing almost at all. I don't know what that guy intended to do but from that source code, it was anything but online ggx .
Besides, my friend modified an open source joystick emulation driver so his keyboard would emulate on my comp the joystick and viceversa. It worked, but since no sync to the games was made, it was so hard for both of us to start a round identically the same so we gave up. I think it might work if you have 2 computers next to each other and only play in one monitor with one game, which kinda solves nothing
