As title states. I bought an snes xband modem that just so happens to have good sram from 1996 with potentially content on it (game patches). I need a way to dump the sram from this thing asap before the 22 year old battery dies. I currently have the modem running in my snes and I haven't switched it off for fear of losing the data. Im not sure this is going to keep the battery alive any longer potentially or not but.. Can anyone help?
