Title: Uh oh. Unisystem problem Post by: DJT on January 01, 2012, 10:17:43 pm Okay. So here's the deal. I got a pcb with excitebike on it. I pulled out my old pcb with skykid, plugged the excitebike in and got nothing but a blue screen :-[
So I troubleshooted it a bit. 1. Pulled the ROMs and ppu off the pcb and put it into my known working pcb (minus skykid daughter board) it worked... So I knew the excite bike game itself was okay. 2. Double checked the original excite bike pcb by plugging in the skykid daughter into it. No dice. 3. Wasn't satisfied with having only one pcb to share between two games, so I tried the excite pcb again and this time I heard a "pop" and smelled something funny in the cabinet. Now none of the pcb's fire up and the screen doesn't fire up. Any idea what happened? Did I screw up the games permanently? How about the pcbs - did anything permanently damage them? I know this may be a bit vague, but I'm scared..is my whole system shot? Is she gonna make it?!? Title: Re: Uh oh. Unisystem problem Post by: John's Arcade on January 25, 2012, 11:14:55 pm Okay.
