How Do You Put New AR Codes On YSMenu ?(for R4)

How Do You Put New AR Codes On YSMenu?So my problem is when I put in a new game with codes i have to make another usrcheat.DAT file.But the YSMenu has one too,and i like the cheat codes it has.But like i said i want too put new AR Codes.The point is when i turn on the DS it works and everything,but 1 of the file isnt working(one of the usrcheat.dat file).Can someone tell me how to make both files work?Or Another way to do this?

My Problems:
I cant open the YSMenu urscheat.DAT file
I cant save the new AR codes to the YSMenus AR Codes

 

You have to recreate YSMenu with the lastest usrcheat.dat
Recreate as in remake the firmware (Dunno how to explain properly sorry >_<)
