well i think i got the answer for you..
get yourself a mini amplifier board like i did, mine arrived today and they run with the gameboy internal 5v.
you can also now use the prosound output from the pot to drive your speaker with those boards.
you dont believe that it can really get so loud that you are not even able to speak to a person in the same room (without shouting) ?
well, look no further... here is the video:
and here is a pic of the wiring and the board inside of the gameboy, i took the 5v directly from the switch and the audio comes from the prosound mod for better frequency response
|easy fit ;-)|
