Q: Can it play all Nintendo 3DS and Nintendo DS games?
A: As far as Nintendo DS/DSi software goes, it won’t be able to play game cartridges that require a specific connections to the cartridge slots, such as the ones that required the GBA cartridge slot on the DS Lite and DS.
Other titles, for example Pokémon Tretta Lab, that requires extra hardware that fit the original 3DS’ shape and size, also won’t be compatible.
Additionally, the New Nintendo 3DS and New Nintendo 3DS XL will not include a charger, similar to the Nintendo 3DS XL in Japan and Europe. However, keep in mind the the 3DS XL included charges in regions such as North America, Australia, and South Korea.
Par élimination on peut supposer que les jeux non concernés seront rétrocompatibles ><.
