So i noticed one of my carts has a pretty bad crack in it. Pretty much one of the pcb pins is gone. One side has a couple mm's left. This is a lagrange point cart so I think its worth salvaging. My idea is to scrap out the pcb making a rectangular gap between the pins. Then cut out a pin from a donor cart and form it to fit in the lagrange gap. Glue the ping into the pcb, solder wires to the new pad to the source pins (bypass the traces) Any thoughts on this plan?
I just took the leg from a resistor, flattened it out and soldered onto what was left of the pin. No need for a donor board.
Thats a good idea that maybe i could use. Although my situation is a little different since have a gap in the pcb subrate that needs to be filled. What is want to do is similar to your pin 25. I could glue my pin and pcb into the gap and solder it to the scraped off trace. I will put up some pics when i have a chance.
If you're not a collector and only care about playing the game then I would get a US NES game shell and one of those low profile Famicom adapters, put it all together and then bridge the broken traces from the game pcb to the adapter pcb with a wire. Print out a nice label and done. Like so: http://nintendoage.com/forum/messageview.cfm?catid=6&threadid=155167 Ofc, that only makes sense if you don't have a Famicom but an US NES console.
if its missing as much as pin 25 then I would be better to scrap out some of the pcb and place a flattened leg in there. a dab of super glue and solder at the top.
