If I change the name of a game...

... will it still work? I really don't like the numbers on the front of the name. Will deleting them affect the game?

If your talking about a ds game then make sure it ends with .nds

renaming it won't change anything but the name, so it's fine
as long as the extention stays the same (e.g. .nds must stay)

k thanks ;D

Also, if you have already played the game and a save file exists, you need to rename the sav file to the same name.
