The Construction Kit cartridge is no bigger than a standard cartridge but it has enough room for up to 30 games at a time. You can change the games as many times as you like - so you will never tire of it!

Cartridge Construction Kit has a 128MB of memory, which can easily be expanded up to 8GB.

Now you can create your own Game Cartridges! Includes 30 mini-games on the supplied Construction Kit CD or download from the hundreds of homebrew games available on-line.

Simply drag'n'drop games onto the Construction Kit cartridge then plug'n'play!

You can even listen music and watch movies on your DS.
