Hmm... I have to admit, I've never tried that one, but I have backed game's up, are these PSP game or PSX games? as the Game Code (region code) for PSX eboots could be the cause.
For PSP, you have replaced the save? Make sure you have played the game already and that the replaced save data is in the same folder with the same names etc.. For instance, if they are zipped then they won't work, they need to be exactly as the PSP would make them, as this is how it will read them back
