GameSpot reports it took Nintendo only four days to sell out the 200,000 DSi handheld consoles it had allocated for the launch in Japan:
The initial allocation of 200,000 retail units has sold out in four days, with most of the sales coming from pre-orders. TechRadar notes that an additional 100,000 units are set to ship to stores in Japan over the next week or so.
A funny note is that the Nintendo DSi has already been hacked. The new console no longer supports flash cards but it didn't take long until someone found a workaround:
According to an unverified Youtube video, provided by one "Yasusoft" (developer of the YSMenu custom DSTT menu) and embedded after the break, the camera-equipped device has already fallen prey to software tinkering. Posters on GBATemp speculate that the hack sore used a modified TIFF image file to cause a buffer overflow.
