According to Develop, Nintendo has decided not to support Flash-based apps on its 3DS hand-held. Echoing Apple’s ban of the platform on iOS devices, Nintendo has decided that it won’t allow developers to use Flash for developing games or other applications. This is particularly important for those wanting to use Flash-based technologies in Nintendo’s 3DS web browser.
On a related note, Nintendo of America announced this morning that it would release a "major system update" for the 3DS that adds the 3DS Internet browser and the Nintendo eShop, which contains a variety of new content, including Pokédex 3D, an application that lets fans see Pokémon characters in 3D. Nintendo is offering the NES game Excitebike re-mastered in 3D as a free download until July 7.
Upcoming Virtual Console content available in the Nintendo eShop includes Game Boy games Super Mario Land, Alleyway and Radar Mission. New content will be added to the Nintendo eShop on Thursdays.
The system update for the 3DS will be available in North America the evening of June 6, Pacific Time.
