Some people who own Nintendo 3DS recently, reporting a small problem of getting a black BSOD, and the language used is more inline with OS X kernel panics than the wall of text from NT kernel bluescreens.
The cause of the BSOD are mixed, but there’re two common culprits. Some players report seeing this screen while playing Super Monkey Ball, while others report the issue stems from Super Street Fighter IV losing a wireless connection and going into a loop. Others also report the issue stemming from bundled 3DS applications.
Fortunately, Nintendo is aware of the issue and has issued a statement to affected customers via NowGamer:
If anyone is experiencing any problems with their Nintendo 3DS console, we recommend that in the first instance they download and install the latest system update, now available online. If the problems still persist we recommend they contact their local Nintendo Customer Service centre to investigate the problem further.
