Hacking R4 cheats HELP!!!

[panmusic]

I have a 8 gb SDHC card and the up-to-date cheat files.The problem is that for an unkonown reason my R4 does not display the cheats for certain games.I have put the games in alphabetical order in the games folder and the strange thing is that after a certain letter there are no cheats at all.I tried YSMenu but the same thing happens again.
I have put the two cheat files(CHEAT and USRCHEAT) to both _system_ and TTMenu folders and tried any different combo with no luck.Any ideas,please?

(sigh) You couldn't have tried Google? Or the search bar? This has been answered thousands of times.

You have too many cheats in the file. Download Yasu's R4CCE (R4 Cheat Code Editor) and use it to open your cheat file. Delete from the list any games you don't ever intend to play, like shovelware, games in other languages, and foreign region duplicates of the games you WILL play. Make sure to save when you're done.

When you downloaded the 'up-to-date cheat file' did you read this notice? http://cheats.gbatemp.net/#notice

... YSMenu solves the cheat problem.
