It's quite possible that this is absolutely the weirdest, yet most incredibly awesome, news DS Fanboy has ever presented. We're going to take a moment to collect ourselves here.
Okay, we're ready to go now. You see, current life obsession for one of our bloggers, the quirky and wonderful Bangai-O Spirits, will have a very unique way of saving user-created stages and replays. The game will output an audio file, through the DS's headphone jack, allowing users to back-up the file on their PC. Then, the audio file can be played back to the DS through its microphone (weren't we just complaining about how awesome the mic is and how it's not being used?).
One of our own came up with an interesting question regarding all of this: what if you took the file and remixed it with a song from, say, the early 90's? What kind of stage would we get then? We'll just have to wait and find out ourselves.
