So again I was about 3 quarters through, and I would turn the machine on, but my game (sonic 2) would not boot up, it's just a black screen.
Now here's the bizarre part. I have the Mega Everdrive X7, and that turns on. But when i select a genesis title, it still will not load. Now what's strange here, is that I can load up Sega Master System games, visual, sound, controls, all work correctly.
Can a capacitor cause the Genesis not to run a Genesis title? Please help, thank you.

I figured it out, my soldering iron nicked a trace, leading from the cpu chip near the cartridge connector. So I severed the section I nicked, soldered a wrote from the pad, followed the trace to the via it went to, exposed the via and soldered the wire to it, and my Genesis games worked again. So I went back, and finished recapping my system.
