FOR FUTURE REFERENCE TO ALL AGETEC MODDERS:
IF you’re going to keep the original Dreamcast PCB inside the Agetec case,
KEEP the original wire harnesses! There’s no reason to throw those out.
Put 0.110 QD’s on the button connnecting wires and the wiring is good for Sanwa or Seimitsu pushbuttons. (NOTE: You will have to cut off the original Agetec QD’s but nobody uses those for replacement buttons anyway! Just cut as close as possible to the original Agetec QD’s to conserve wiring and you’ll have plenty of the original wiring left to attach to the replacement buttons.)
As for the Agetec original joystick wiring, cut the wiring as close as possible to the joystick itself. BUY a European terminal strip and connect the original Agetec joystick wiring through that to the Sanwa/Seimitsu 5-pin harness.
If you do this, there is NO SOLDERING REQUIRED for this mod!
This works perfectly fine if you keep the Agetec stick’s original PCB… On the other hand, IF you install a Cthulu PCB or MC Cthulu PCB, you will have to do SOME soldering but not a lot… You really only have to solder an Ethernet cable (if you go RJ45 route for MC Cthulu) or a USB cable if you go PS3/PC/Mac Cthulu.
