Nintendo Japan Starts Store-Based GBA Wireless Network
Thanks to Planet GameCube for its article discussing Nintendo Japan's rolling-out of the store-based JoySpot service for the Game Boy Advance wireless adapter. According to the article: "Consisting of wireless base stations - also known as hot spots - at retail locations around the country, JoySpot acts as a miniature server and hub for GBA games supporting the wireless adapter." Although players can use the limited-range wireless adapter with friends separately of the JoySpot locations, "...players can download news from the JoySpot station in Pokémon Fire/Leaf via the virtual JoySpot kiosks.. [and] can also take part in special JoySpot challenge battles among other gamers within the station's range by talking to them in the [virtual] union room."
The N-Gage might have Bluetooth capability, but how often do you find someone else with another N-Gage, let alone the same game, let alone that they're willing to play the game with you?
Goo goo g'joob.
From what it seems, the only things that will occur through this link will be some battle/competition events and some news updates. The fact is, these are already manipulable via GameShark, so there is no need to worry.
To be honest, I don't think Nintendo will do anything in the fashion of making hidden, unlockable features only accessible through this feature--but if someone is desperate enough to use a GameShark with the wireless link, they're better off just hacking with a GameShark on a static game.
For reference, most codes are trained by switching to different scenarios where the value you want to find is different, then modifying those values by GameShark and finding the correct register through process of elimination. In a wireless environment, one simply does not have the freedom to restart games and slowly try different registers without seeming suspicious. Also, unlocking these features should be done on a static, unnetworked cart (this is for cheating, after all).
