Someone with more knowledge please correct me if I'm wrong as I'm not familiar with 3DS hardware or with how fire emblem saves data, but it doesn't seem that this game's save file size should be excessively large. Skyrim's save files for example, can be something like 15Mb+ and higher with mods which is understandable considering how many unique variables there are (and being a poorly optimized game in general). Fire emblem needs to record things like supports, stats, game progress, inventory with weapon uses, ect. It doesn't seem to me that fire emblem requires large amounts of data for each save file. The 3DS cartridges can potentially store 8Gb at best and the vanilla game size is 1.3Gb so even if we aren't in a perfect world and have 8Gb available it doesn't seem impractical to have more than 3 save files. Again, if someone more informed than me can tell me otherwise, please do as this really bothers me.
