It should be backwards compatible with all DS and DSi games. However there are a few things that can't be supported:
A Nintendo eShop card is the same price as the amount of money on the card. For example if the card has $20 of eShop money, it will cost $20 real dollars.
Yes, you can download Kirby Triple Deluxe on the Nintendo eShop at a MSRP of $39.99 (CAD/USD)
Firstly, you will need internet connection and your region settings must be in a location that has the Nintendo eShop available. Then, select the Nintendo eShop icon on the home screen. Enter your Nintendo Network ID and password to have access to the Nintendo eShop.
$20 for USA and Canada. I'm not sure about other countries.
To add funds to your Nintendo eShop account, you must either have a prepaid Nintendo eShop card or a valid credit card. After launching the eShop, swipe to the right or tap the menu button to find the "Add funds" button. Alternatively, if you're looking to buy a specific game, do not have enough in your eShop account, and are paying by credit card, you can browse to the game you want to buy, then tap "Tap here to purchase." When the eShop tells you that you do not have enough to buy it, choose to add funds to your account, select "credit card", then select "needed" to add exactly as much as you need to buy that game. Remember that your eShop account is tied to your 3DS and cannot be used on another system.
