Re: Shining Force: every game chapter gets its own save, and those saves are big. The Sega CD has enough internal RAM to store one chapter's save with a little leftover room, but not more than that. Since accessing chapters 3 and 4 requires a completed savegame from chapters 1 and 2, you basically have to have a RAM cart to get the entire game. If you only care about the main game you can squeeze by without one, though.
