Putting in new cheat codes on R4

As the topic would suggest, I'd like some help adding cheats to DS games on an R4. The tutorial was a bit over my head, and when I tried following it, nothing changed. Lots of games have codes already, but they're all in Japanese so unless it says "HP" or something, I'm completely lost.Any suggestions?

Get a usrcheat.dat database from http://cheats.gbatemp.net/ and put it in your _system_ folder on your MicroSD.

Oh my good God, that is a LOT easier than inputting them myself. You sir, are my savior. ;D
