What does this mean?

Okay, so I just got my M3 and Passcard 3 combo, and it is working great and all, but whenever I turn off the system after using a homebrew and turn my system back on, it says on the screen:

Beup Live 0.3.nds

Warning! NDS GAME SAVE in card but CANNOT find 'NDSSAVE' directory. Backup fail! Press A to continue.

Now the Beup Live 0.3.nds was the last Homebrew I used before I turned off the DS. Please help me with this.

 

Did you use the Game manager to write the NDS file to your media card? If not, thats the reason why. It creates a save file for it whenever you use the game manager. Delete beup from your card, and rewrite to it using the GM

 

Okay so when I put it on the DS through the Game Manager, what do I want to put all the settings to? Also do I say "Write NDS" or "Write GBA"?

 

for homebrew it doesnt matter if you have that save error.
but for roms you need the save.

 

just put normal mode without any options ticked.. i prefer to have the autosave thing on there even though its not required.. just one of those things
