Multiple nds files in a game

Why is there multiple nds files when i download a game rom?
Can i only put one? and it will still work?
or do i put all of them?

 

There is usually only 1 x .nds, you may get other files .sav .info ets but only one should have a .nds at the end

download evolution tools from cyclo (if you have a pc) when you install it you can tell the pc to associate .nds with evolution, you will then see the icon for the game and you can also get the game info. This will tell you if the game is genuine (does not work for DSi roms)

 

It doesn't work for DSi?
well that's what i have, you know of any other program like that? but for DSi roms?

 

Are you sure that you mean multiple files with a .nds extension, or just multiple files?

AFAIK, there are no .nds ROMs that come as more than one file.

 

Well the ones i have do! and they are all .nds files with the same name and same size!
