help! with ds using passkey, can't boot games!

I'm using passkey with a 1gb cf card freshly formated with fat filing system. I use gamemanager v21b to write games to card and when I go to load games I get nothing but white..I'm using an old ds too any assistance would be appreciated...

 

is it a passkey one or two, and are you using a ds lite or normal ds? most likely the problem is that your using old gamemanager and firmware. download version 29 http://www.dualscene.net/infusions/pro_download_panel/download.php?catid=4&did=132

 

what flashcart are you using.

 

game manager and 21b -> M3. He was already pointed in the correct direction... useless post.

 

pakixd, why do i get the feeling that you dont like me?
how was my post useless. i was only trying to help. i thought other flashcarts have game managers too.

 

a little more info might be helpful.make and model of flash card/passkey/card
is this a new flashcard(m3?)/passkey setup or an old one that stopped working?
if its an old m3 one did you recently update it?
