i just wanted to know how you can make a nes four score to usb, i seen one at http://www.sealiecomputing.com/retrozone/fourscore.html for sell for $50. they all so have the parts to make one but its 16 bucks still to much for something i could make. i have one, that uses the lpt port (db25). but it doesn't fully emulate in software. does any one have the plans for this.

thanks
ryan
