While the DS homebrew and hacking community doesn't quite hold a candle to the PSP's, there are still many a soul who live to exploit Nintendo's wonderful hardware. While many have managed to perform "good" by enabling things such as emulators and voice chat, there are those who would do malicious evil. This is one of those cases.
A hacker named Legacy has released an application that grants players in Metroid Prime: Hunters access to several cheats, including infinite energy, infinite ammo, and levitation. Worst of all, these capabilities are also accessible in official Wi-Fi matches; before long, you may see a few of these cheats yourself. Tsk tsk, Legacy. Got rocked a few times too many?
