There are two sides DSRemote operates on. The server must be run under Windows (preferably Win XP), while the client (the DS app) must be run on the DS. So how do you run the DS app on the DS? Well, first of all you must have a way to play homebrew application on your DS. For this, you will need to either flash your DS, use Passme, or have a compatible wireless network card. If you need help with this or I think a lot of people on this forums are able to help you out with this. Secondly, you will need a way to store the app. This can be done with a flashcard or a gba movie player, once again, people here can help you with this. To use the wireless apps like DSRemote, though, a Ralink rt2500 compatible wireless network card is compulsory. Good luck!
