R4 Pokemon Cheats Not Workin

I've just downloaded the cheat database for my R4 (usrcheat.dat) and all cheats are working except one in pokemon diamond/pearl. In the wild pokemon mod codes it onlt goes to hitmontop, but when I look at it on my computer all pokemon are there...can anyone please help? :'(

Using the right database for your version of Diamond? On the other hand, could just be a bad code, or you have too many codes enabled.

Ya its the right one, the codes match up if ya know what I mean! All other cheats work on Pokemon diamond. This one is like a drop down menu with bout 300 or more cheats in it, but it stops after about 200...I hope you know what I mean coz its hard to explain!

Hm, unfortunately, the R4 has a few issues with reading too many cheat codes (and their descriptions), so I'd recommend you open up the usrcheat.dat with R4CCE (google), and then delete some of the codes that you wouldn't use.
