Found a way to play online (for people that can't make a WEP hotspot):If you have a newer phone, you can probably only make a WPA2 hotspot, but I found a way how to make it work.You need to make your network open and you need to add your DS mac address and put "Allowed devices only". You can then connect your DS without a problem to your hotspot and play any game you want online. Tried it with MKDS and played a game with someone online and it worked great!Hope this helps
