As taken from my post over at gbadev topic link here: http://forum.gbadev.org/viewtopic.php?t=12282 .

I've found that the SC SD contains a DRAM chip where it stores its save data. The Chip ID is hy57v561620ct-h for those who are interested in googleing information about the DRAM chip. Now, this is where I stop at. I have very little hardware knowledge and I need help on which pins to solder the cords leading to the battery. I've taken a battery from another GBA cart assuming that it would work. Any suggestions?
