If you have a slot-1 flahscart, be sure to use the "no save" version.
Hey! That looks like a nice game, but what exactly does the guy mean when he says, "Be carefull! This game uses SRAM for saving and doesn't give a warning or anything like that before formatting."?
Erm...before formatting what, my flashcart's memory card? Do I have to worry that it will wipe everything on the card? I would rather play the version that saves, but I need more info about this warning. Anyone know what he's talking about?
