Honestly, what I would love to see more than a cheat system implemented into AuRei, is the video streaming feature from NTR's preview builds. I feel like if it was integrated into the system, that would increase it's stability 10 fold, considering the fact that as it stands now, you may be able to get a stable 30 FPS streaming, but if you exit the game, and open another app or game, the 3DS will freeze on the "Nintendo 3DS" screen with the red lines, and the only way out of that is to just shut the DS down. As well as the fact that currently, if you are using the video streaming from NTR and you close your DS, and open it up, it stays in sleep mode.
I just feel like these features should be part of a legit CFW, not something thats run as basically a background process that breaks some things with the system until you do a hard reset. Don't get me wrong though, I do love what NTR has been doing.
