how do i add an AR code to my r4ds's cheat database

i found AR codes for Rune factory but cant figure out how to add them 2 my r4ds i appreciate any and all help

Download the cheat code editor of the official r4 website then open it (no installation) then create a new database. Add different folders for each game you want cheats for, then insert the name of the game then the game id. There is an option on the editor that can browse for nds roms and check their ids. Go to codejunkies site and look for the game you want. Make sure the game id from the page matches your rom's game id. Use the AR cheats from there and copy and paste into the database folder for it. Enter a name for it too. Then save it as usercheat.dat and put it in the system file I think (it worked for me) and voila! it should work. Very easy to do.
