Actually I do need help =/

Anyway. I have the CHEAT.dat file from GBAtemp and i did what the sticky said which was delete games till the file size is under 4mb. I did this and the cheats for the game i want (Yu gi oh sprit caller) still wont show up. Can anyone help me with this? Thanks in advance

I'm assuming you are using an R4? Use the r4bugfix2 to fix the cheat database file size issue without having to delete games from the list.Just google r4bugfix2 and you'll find it.

I just did that now and it didnt work =[

Try making a usrcheat.dat with only the Yu-Gi-Oh game's codes in it. Make sure to have 'Game Enabled' option ticked with R4CCE by Yasu.
