sega saturn

i've been playing dragon force for the saturn lately and i'll save in the archives but after a while when i turn my system back on my saved game is gone. i was wandering if this problem could be fixed simply by buying a memory card or is there something else i can do??

the saturn has a battery inside of it??

seems like googles says there is.

but now that i think about it, i dont know if your really need that for save games??

maybe you do need it.
