We’re working hard to create a new programme, which we plan to launch later this year. And as a special offer, users who sign up to the new programme during the launch period will be able to download Flipnote Studio 3D to a Nintendo 3DS system for free. Please stay tuned to the Nintendo website for further details.

As a gift to Club Nintendo members, the Flipnote Studio 3D software will be available to download for free in February. This software will allow users to create unique three-dimensional animations and to exchange their creations via local wireless with others who also own Flipnote Studio 3D. Users who uploaded creations to Flipnote Hatena will be able to download their personal animations from the Nintendo DSi Library menu in Flipnote Studio 3D software. Flipnote Studio 3D will be available to Club Nintendo members until June 30. The ability to create a new Club Nintendo account will end on March 31. All users who register to Club Nintendo before registration closes will be eligible to receive Flipnote Studio 3D.
