Hell, i am so interested on the SGX+CD combo, that to sweeten the deal, i could also add a half working-PCEngine Duo. I tried the cap replacement on it, because of the no sound issue, but i suck at soldering and blew a diode, and now it doesnt play discs, and i just did a poor job soldering the caps overall. It still plays hucards though, and before the diode problem, it played discs fine. Should be repairable by someone with actual knowledge.
