Hey all,
I've been tinkering with Sega Genny boards again, and was trying to replace the BA6162 battery supervisor that they use in their boards. I figured that a diode setup similar to what is found in the NES would work...but it doesn't. Well, the game holds a save, but if you power it on and off a few times, or run your finger along the contacts on the cart the save disappears. So it KIND OF works, but is extremely sensitive. I've used the same method in SNES carts with 256K SRAM before and had no issues, though.
Here is how its wired up:

Any ideas on what else I'd need to do?
