Start my NDS games

Hi, I have a DS with G6 and a passcard. I think it is called a flashcard the G6.

When i download NDS games they dont work. Putting the games in the DS is no problem but when I start them it is just black.

What can I do to get them work, some games work but just the old one like zelda, new mario, etc. Not the new ones like GTA chinatown wars, lego indianjones, kungfupanda.

Can I upgrade the G6 or what can be the problem?
/thanks
