Nintendo’s dual-screen DSi was released in Japan yesterday, and several flash card devices were tested on the system. The results were bad, with every single device failing on the system.

R4 – Failed
EZ Flash V – Failed
CycloDS – Failed
G6 DS Real – Failed
M3 DS Real – Failed
Supercard DS One – Failed
iTouch DS – Failed
FCard – Failed
NCard – Failed
M3 DS Simply – Failed
U2DS – Failed

There may be more that have yet to be tried, but as for now, the DSi seems to be impervious to the wonders of pirated flash cards.

Nintendo has narrowed the stateside release of it’s DSi handheld to summer of 2009, according to company president Satoru Iwata. Meanwhile, the unit sees release in Japan tomorrow. It will be priced at about ¥18,900 or $192. Nintendo has already shipped 200,000 of the slim, dual-cam handheld device with another 100,000 to follow next week.
