HELP: Only loading a few of cheats that I put onto usrcheat.dat

I can only load about 5 out of 13 cheats that I put onto the usrcheat.dat file. Does anyone know how to solve this problem???

Are the GameIDs correct? Do you have an R4?

Yes I have an R4 and all the game IDs are correct. Could it be something wrong with the CHEAT.DAT?

Did you make this database yourself? Are the Game Enabled boxes ticked for each?
