i got an idea about game saves, but its not for all

[whackawookie]

so im going through my action replay instructions and i came across a section that said that sending a save file to the wrong game could ruin the game. so i started to think, well would the save still be present. only downside is if this infact works, then u would have to send a save file to the ds cart for the game u want to play, then choose erase in the game settings. the only game i was eager to try it on was metroid demo, but i think the save file is very small, so its not working good. maybe a game with the largest save size would work, but i only have 3 ds games and only one id be willing to think about trying it with.
this also would only pertain to those fortunate enough to have the action replay. this may not work at all, but its just a hunch

sorry didn't catch what you said.

So you send the save game then erase it, what does that do?

[whackawookie]

no send it, but then clear it IF u want to play the game new, u know without the content from the save file

Another method would be to buy 4 different games that have 4 different save types (if there are only 4 maybe much more) and then you could save every game to it you just have to find out which save type is supported by which card. I know this sounds expensive but nearly everyone will atleast buy 4 games if they are exclusive like zelda mario sonic etc. and then you could save. But this would only work if there are only 4 different types maby there are less or more. So now nothing is known about save types as yet but there should be some lists soon like with GBA what savetypes each card has. And maybe in the future someone will produce and empty flash card which can save every game to it.

oh, okay. I get it know.
