ok, here is my problem, I own Shadowrun and the battery must be dead as it will not keep saved games anymore, I have nothing to open the cart with anymore as I lost the damned screwdriver that can open these. After I clobber the hell outta it and finally get it open what should I expect to find? a soldered down battery or what? I need it replaced asap. If I remember correctly my SNES games had ways of replacing the batteries once I got them open, but its been a long time since I opened a cart of Genesis or snes. any help will be appreciated.
