First, get all the proper files. PPjoy, DSpad, and DS2key. Ok, let's start. 1. Install all the files in their proper places. PPjoy- PC DS2Key-PC DSPad- DS (Be sure to apply DLDI) Once you've installed them all, make the file works on your DS. Don't connect just yet. 2. Go to your router's firewall settings, and look for something that allows programs through it. Set it as these settings: Name: DSPad02 And set the ports to: 8888 3. Now, open command prompt, and enter ipconfig, you should get a bunch of mumbo jumbo, look at the top for your IP address, it looks like: IPv4 Address . . .
