Installation Tips

  • Do not take the GBA-SP screen apart; it is only necessary to disassemble the base
  • You may need to use some electrical tape between the GBAccelerator and the cartridge connector to prevent accidental contact
  • 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 white areas, screw holes, or tall components
  • Cut off excess wire length
  • The three button connections on the GBAccelerator are interchangeable; it does not matter which one goes to which button
  • If alternate button assignments are desired, see button signal list for available connection points
  • You may need to trim some of the plastic standoffs from the back cover of the GBA-SP if the cover does not seat properly upon reassembly
