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 GBA 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
  • If using normal control mode, the three button connections on the GBAccelerator are interchangeable; it does not matter which one goes to which button.  If you wish to use up/down control mode, make sure the correct button inputs (Select, Up, Down) are connected to the desired GBA buttons
  • If alternate button assignments are desired, see button signal list for available connection points
