Outdated/Annoying gaming mechanics?

[Jolly Co-operator]

Quite a specific one, but why can I only have one save per game in pokemon games? I understand back in the Gamebot/GBA days, when the device didn't have its own memorey and space on a cartride is limited. By what harm would there be in letting me use some of that SD card in the DS for multiple save files?

I can't remember where I heard this, but I think it has to do with how the data for individual Pokemon is stored. Something about the method would potentially be too much for an SD card to handle if two save files were made (I apologize if I'm incorrect, but I do remember hearing something along these lines, though. Sorry I can't give a more reliable answer).
