Allright! I think I can start to see what's going on here.
However, I'm admittedly pretty new to this whole repair thing. ;^^
Can anyone link me to a guide, perhaps, showing the correct way to open up these things and exactly what to look for? Surely someone somewhere must have had problems similar to mine in the past. It would be much appreciated.
Oh, and I've already removed my genesis for nowWould be quite a hefty lid to remove from the SEGA honeypot when peering inside otherwise. To be completely honest, yet another reason I want to fix these is that, without the SCD, the Genesis' expansion port is bare, ugly and vulnerable, since there appears to have been no side cover in the lot.
