Eh, I figured as such, but for many games this really isn't an issue. For every game like Metroid or Castlevania, which you need saves in this day and age there are dozens that don't, like Super Mario Bros., TMNTII, ect.
So long as you aren't giving it as a gift to a non techie, I think most people really only need 4 saves total for the entire library. After all, you only play one of the longer games at a time.... or at least I do.
