60 to 72 pin Adapter Nes

[jonjandran]

How difficult would it be to put a 72 pin nes where a 60 pin Famicom connector is ?
Is it as simple as connecting the appropriate pins together and leaving some out.
The reason I ask is I'm trying to be able to use my nes games on the Famicom only Game Theory Admiral. ANd No, adapters don't work. So I was hoping to take off the 60 pin connector and put on a 72 pin one . I just need to know which of the 60 pins to solder where on the 72 pin.
Any ideas ?

Thanks , that helps.
I've almost got it working.
It has garbled graphics and no sound, but I'll keep trying.
