Hey! Good news about those save files, the game has the option to save/load from disk, so you can create a folder for your characters and have as many files there as you want. The saves won't appear on the list when you press saves, but if you chose the load from disk option you can access them. I use this to have a folder for each MC in order to play all routes. Or just name the file by MC-Chapter number. Hope it helps :)
