R4 problems

Most games I download don't work on my r4 especially the ones with the numbers, can someone help me? I am getting tired of this because I am missing out on my favourite games.

need more info.. just an r4 or r4i do you have the newest firmware?

Also, do you use an DS, DS Light, or DSi?

Add wood or ysmenu (depending on what your R4 Cart is)

I have ds lite and i got the normal r4. I am not sure if I have the newest firmware as I havn't done anything to it after I got it.

YSMenu is a good choice anyways, it supports latest games if updated,
if you have an R4 original, then You can also use Wood R4: http://forum.romulation.net/index.php?topic=39701
Could you tell the text that is written on your flashcard? like R4DS Revolution for DS ect...
