I'm guessing that since it's USB, you're effectively remapping the keyboard such that each of those buttons activates the closure on a regular keyboard disassembled and hidden underneath.
So ... $10 or less for a new USB keyboard to disassemble, 25 single pole, normally open, momentary push buttons at a retail of $4 each, 6 single pole, normally open, momentary toggles at retail of $5 each, and the joystick, about $10 retail. About ... 50 feet total of 2 wire 18 gauge, some solder. About right on the parts list?
Note - I'm throwing retail prices out there for these items so that the guys that want to build this have an idea that from a retail perspective, it's more than $125. (Luis!)
Wholesale - I work at an electronics distributor, so ... less.
