Few questions regarding flashcarts

I'll get to the point:
Do you need to chip your ds for carts to work?
If you do, does the netstuffs still work?
Any places to get a cart in London?

Thanks,

No you don't need to chip your DS.
I'm not sure what you mean by "netstuff" though.

 

I think he mean Wifi-matches or the online-functions of the DSi.
You only have to buy a flashcard. Cyclo DS for DS/DSLite or "ask another guy with a DSi for recommends" for DSi.
You dont have to open your DS for use them, they are like cardridges with a place for a Micro SD, where you can put on all the stuff you want to use (games, homebrew...).
You can go online with your DS and a flashcard without problems.

Edit: Best place to get a flashcard is the internet. On Amazon for example, you can buy near everything.

 

Here,if you're getting a DSi.

Apart form flashcarts ;D

 

Oh my god, youre right. I only looked at amazon.de where you can buy all these stuff and not at amazon.com
My fault!

 

Their not on eBay either nor Amazon.uk.Probably because on legal grounds.
