5 player Duo mod.

[CrackTiger]

Do any of the experts think it would be possible to mod a Duo Tap into a Duo system? Ideally so that there are 5 holes in the front like an N64 or Dreamcast.

If not a Duo, how about a TG-16, SuperGrafx or some other system?

If this mod was done on a TG-16, I'd suggest using a Duo Tap so the user doesn't have to track down so many Turbo Pads.

This kind of this has been discussed before, and it's always ended with the mutual agreement that it's not a good idea. Some early games don't cope well with the tap plugged in, such as China Warrior.

The TG16 has probably the most room to play with, so I'd go with that if I were to do such a thing.

I suppose one can build in a switch on the bottom of the unit to turn off the other 4 ports to make the circuitry go back to its original state for games that have issues with the tap. 

Sound like an interesting idea, but I'm not so good with a dremel.  I'd pry have 5 holes all out of line & in different sizes.

Beyond the problems that have already been mentioned, one advantage the "real" Tap had was that it added a little bit of length to all the controllers. Without a physical tap, you and your buddies are going to have to sit that much closer to the system/TV unless you want to hunt down extension cords for all your controllers.
