N64 Controller and rumble: Is it Possible?

[ulaoulao]

For example (dumb question incoming), what is a port; is it the place the controller is plugged into? Can you have multiple ports on the bliss-box for different consoles? And why is it that two players aren't possible; I didn't understand that part. Is it only possible if someone had two or more bliss-boxes?

Port: nes,n64, sega, ect. A port is what just a way to connect a type of controller. With Bliss-box you get many ports to one USB adapter. Only one port maybe used at once.
Player: Just as you would think its the USB side of it. A 2 player box has two usb ports in side.

With a single player you can use any controller out there and the computer see it as a player.
With a multi player you get any controller out there per player, the computer sees X player. A 4 player = 4 devices to the computer.
