We had scheduled wireless multiplayer for the next release of Laser Hockey DS. In fact, our initial goal was to get multiplayer working as soon as possible and then work on other niceties such as graphics and physics. The reasoning is that we want to make sure our very base game engine is multiplayer-friendly before we add features. However, this goal is not possible with the current version of the homebrew WiFi library. If you have any time, money or expertise please give a hand to sgstair over at 1Emulation. His library is now included with DevKitPro. Click here to jump directly to the WiFi forum topic.
Since our goal is not possible, I guess we will have to do some work on other parts of the game first. A title screen may be in order.
