i have a 2 part question the first one is. does the turbo-duo have internal memory for saveing games or is there a special accessory. for instance i can't sem to find a menu to access any internal memory if there is any like i can with a sega cd or like system. i'm planning on playing some rpg's on the system like Ys and i assume its going to take longer then one sitting. it did hold a save for dracula x for me but after playing again today (first time in a few months) the save was gone so i'm thinking it only saved while the system was on? like rom memory
second part of the question is anyone know the average time a save will last for a nes cart or for that matter any cart? will it be worth buying a nes RPG in a few years if the save feature does not work or will we just be better off playing on a pc with a rom? does the battery memory last as long as the game lasts? can it be replaced?
