Installation Tips

  • Use low-wattage, fine-tipped soldering iron
  • Use flux or rosin-core solder
  • Don’t hold the iron on the GBAccelerator or the Game Boy board too long as you may lift the solder pad
  • Solid 30-gauge wire is recommended
  • Follow wire routing indicated in diagram so wires don’t cross button pads, screw holes, or tall components
  • Cut off excess wire length
  • Some of the solder points may be covered with green solder mask.  Use a blade to carefully scrape away the mask without damaging the copper pad underneath.
  • When reassembling the two case halves, make sure the LED wire doesn’t get pinched or interfere with anything
