N5 ar codes?

google R4cce, thats a program to edit cheat data bases, then you will need a cheat file, find it here--->http://cheats.gbatemp.net/Temp/

downlaod the one above the .xml one, and then erase your own cheat file from your N5 it should be on the system folder, then drop it to the trashcan, subsequently erase it, then all is left for you to do is to put the new file the N5 has a glitch that wont allow it to read certain databases of a great length, so all you need to do is use R4cce to erase the games that you wont play and elft those who you will be using
