Ok, well, I recently got my hands on copies of Sonic 3, and Shining Force 2. The backup batteries in both of them are dead, which isn't a HUGE problem in Sonic 3 (but I'd like it to save anyway), but in Shining Force it's a must. I've heard that you CAN replace the batteries, but AFIK they're soldered on the board, and you need to get the cart open first. (I know you need a GameBit, and I know a local store who will open the carts for me) Does anyone have any info on replacing the battery, or where to get it done? (If you have any info on doing the same for SNES and GB, please let me know as well, it could come in handy) I want to play Shining Force 2 on the original machine!
