Nintendo DS Classroom

The Nintendo DS(i) Classroom, also known as v1.4J_kst is a specialized DSi version used in Japanese schools. This version contains many differences from a retail unit, including some applications exclusive to this version of the DSi.

"DS in the Classroom"

On June 9th 2009, Nintendo announced they will parthership with Sharp System Products to create a Nintendo DSi for use on Japanese schools for Japanese children in elementary schools, junior high schools and high schools. Simply codenamed Nintendo DS Classroom, the unit would promise that teachers can use the DS Classroom on their PC so it will communicate with Nintendo DS's with a DS Classroom cartridge or with Nintendo DSi's with the DS Classroom app installed as DSiWare.

Furthermore, Nintendo goes on to say that Sharp System Products would work on 60 applications offering a variety of subjects, such as languages, math, history, and more. The system would then launch on February 2010 in Japan.

Nintendo DS Classroom application

The DS Classroom application opens up as a Nintendo Zone-looking UI and it will start searching for computers connected over the same Wi-Fi connection. The application would work as interactive tests made by the teacher and the teacher would be able to view scores and rankings, similar in a way of Kahoot and Nearpod.

(Re)discovery

On May 27 2019, Voodooween had a conversation with Trash_Bandatcoot about DSi system versions. On that list was a version known as v1.4J_kst, he also revealed it had some DSi software used by students. A day later, he sent photos with a NAND dump, by using the Flipnote Lennyface exploit. A lot of research was done the same day by the TWL Hacking Discord server revealing that some of this software was also sold seperately as a NTR cartridge, meaning these applications are also on the Nintendo DS and DS Lite. However, the PC software for the Nintendo DS Classroom application remains lost.

General differences

Besides the system menu version, there are differences on the system menu as well.

• The unit has a sticker on the back giving instructions to the Nintendo DS Classroom application.
• The Nintendo DSi Shop is not present, preventing students from buying DSiWare.
• The internal NAND comes bundled with the software selected by the school, as well as the Nintendo DSi Browser, Flipnote Studio v2.1 and the Nintendo DS Classroom application.
• The “System Management” option is gone from the System Settings, preventing students from copying application data to their SD Cards.
