problems with r4 chip not working

hi all i have a 1.18 version r4chip and games that i download from here don't seem to work can anyone tell me why?????????????

We need more info.-what ds system are you using?
-What does the r4 label say (you might have wrong firmware-the r4's have many fakes)
-What games (might have priacy protection)

it's a ds lite , r4 chip says r4 revolution for ds (ndsl/nds)
tried many games so far none have worked i have no idea what i'm doing wrong...grrrr

Replying to #3

What games are they exatcly?List a few...I know mario kart would work instantly...unless the firmware isn't installed properly.And did you "extract" the games via winrar/7zip?
