Thanks to 1UP for its article revealing several new technical details
regarding Nintendo's just-announced
DS dual-screen portable. In particular, Nintendo of Japan noted the DS will "...have two different processors, an ARM9 main CPU and an ARM7 subprocessor. Both of these are used in many cellular phones, PDAs, and other mobile devices - an ARM9 CPU is the heart of Tapwave's new Zodiac handheld, while the Game Boy Advance employs an ARM7."
It's also confirmed that the screens will "...both be equipped with a backlight... with a light source behind each LCD. The Game Boy Advance SP, by comparison, uses a frontlight."
Game Informer has an interview with a Nintendo of America spokesperson
which reveals a little more, including confirmation that the screens "will be in the vertical position"
, not "side-to-side."
The piece also features the spokesperson stopping short of a denial about GameBoy/GameBoy Advance backwards compatibility ("We haven't announced anything about that, yet."
