The new Nintendo 3DS Game Cards also known as N3DS Cartridges.
At E3 the big N revealed that Nintendo 3DS will have its own separate Game Cards. The Game Card Nintendo 3DS showed will at its release have a 2 GB max capacity, that is much larger than the Nintendo DS / DSi Game Card, but similar to the R4SD flash cards that have been used by DS homebrew fans and will sure be tested buy 3DS owners. It assumed that this Game Card was designed to to stop piracy. It is known that anyone can "hack" Nintendo DS simply and without much knowledge, by just purchasing a R4 SDHC card adapter and copying NDS files from the Internet (no real hacking involved and DS does not even have to be modified to run pirated game backups a.k.a. NDS roms).

There are people who buy the Nintendo DS and will buy 3DS, with the sole purpose of running game backups on it, and having an extensive library of all DS / 3DS games on its for free. The is speculation about Nintendo is again trying the battle widespread piracy in the fan-base and stop it with the introduction of its new Nintendo 3DS Game Card, but it will not be as easy at it looks. First of 3DS comes with backward compatibility and as such it will run DS and DSi game cards, so R4DS, R4i SDHC, AceKard 2i, EZ-Flash 3, CycloDS, SuperCard DSONE and DSTWO will all be able to run Nintendo DS games on the 3DS. Also 3DS game cards are near identical to NDS cartridges except for a little tab on the right side corner that is there for ONE purpose only -- to prevent you from inserting a 3DS game into a DSi that does not support it and than calling Nintendo and complaining that the game does not work. But there is nothing preventing you from putting DS cartridges into 3DS and as with DS that initially could play NDS roms (game backups) from a rewritable Gameboy Advance cartridge also known as GBA Flash Linker card so will 3DS will first be attacked by R4DS flash cards that will be backward compatible with all versions of 2D DS and will attempt to brake 3DS copy protection.
