Quoted from Gorno:That SIP resistor solution looks like such a pain in the ass to solder. I wish there were a easier solution that was still that cheap.
There is a fairly easy solution, but you have to be willing to cut up some stripboards, and solder some SIPs (or resistors) and headers on them. A whole game could be done for around $5 in parts.
It would be a nice, easy starter project for anyone wanting to practice some basic soldering, and you wouldn't risk damaging your game board:
Stripboards -- $1.29 (say x3 is $4 -- if you cut them right, you'd probably only need one though)

NOTE: the smaller, 66 cent stripboard won't cover all the 28 pins on the JX connectors, so if you use those, you'd have to cobble them together somehow.
the SIPS or discrete resistors --
(don't have exact amount, but 63 resistors X .01 is less than $1--SIPs may be more)
male / female headers -- $0.15/$0.24 each 40 pins (x4/x4 is about $1.60)

DISCLAIMER:I haven't made these, so the information above may not be 100% accurate--but it should get you in the ballpark. If you decide to try this, please research it so you know exactly what to buy, and how to put it together, and thoroughly test it before connecting it to your game...
