I honestly didnt think to check that LoL. I will check into it and let you know. Either way its not too difficult to replace the battery inside. Its just a standard CMOS type battery like on a PC motherboard. CR2032 is the size, you can buy them at Wal Mart cheap :)
Ok, I am happy to report that the SAVE does appear to be functional. I just played through to the first save point and after taking the game out and putting it back in, the save data remained :) YAY... On another note, I forgot how difficult this game was... I was starting to get frustrated trying to get the save point LoL...
