R4 Help needed.

1) I can put AR codes on my R4, but sometimes THIS happens (See 2)).
2) THIS = I have 3 games on my R4, and 3 games in my CHEAT.DAT file. Then when I add it to my DS, one of the games' (Final Fantasy IV) code lists couldn't be accessed, while the others could. I switched some codes around later on and re-added the DAT file into the MicroSD, and now the game (FF IV) I couldn't get the codes for were accessible, but now one of the other games (Fire Emblem Shadow Dragon) isn't working for codes (Can't get into the list). Can anyone help? GBATemp hasn't been able to help me yet and I can't get any help from Google or Digg.

Sorry if you can't understand my predicament.

EDIT: I deleted FF IV and its cheats from the CHEAT.DAT file, but I still can't see the codes for FESD.

 

Get the usrcheat.dat. Modify it if you want with Yasu's R4CCE (google), ie delete some tables etc.

 

Thanks. If it works or not, I'll tell you.

EDIT: Sorry, no it didn't work.

 

Just get the usrcheat.dat again from cheats.gbatemp.net and overwrite. Should work fine with all 3.
