Buy real ds games and use them until you get your card, if there is an eb games near buy you can return within 7 days and get your money back.
What you have to do, is get a life. Maybe do some walks in the park, get something to eat. Or better yet, watch some TV.
Maybe you need a new hobby. Have you ever tried paper crafting? This is fun and does not cost too much. You will find yourself not getting enough sleep because you want to complete it. http://www.yamaha-motor.co.jp/global/entertainment/papercraft/realistic/index.html
What did you expect? You claim your bored with your NDS and ask for others suggestions without really being clear if your are totally bored with just the games you have, or with playing games all together. Then you want to complain about suggestions that were made (and besides you should have expected a smart ass response.) If your truly bored with the games, maybe a new game genre would help or find a new console/handheld. If that is not the problem then it might be best to take a break from gaming for a time and find something new then maybe come back to it, its a rehash of whats already been stated so other than that I really don't know what else to tell you.
