The Nintendo DS Rumble Pak is incompatible with the Nintendo DSi and Nintendo DSi XL, as both consoles lack a SLOT-2. However, none of the games supporting the Rumble Pak require it for proper operation of the game, meaning that the games themselves are still compatible with DSi (some software titles, such as Nintendo DS Browser and "", have SLOT-2 peripherals that are required for operation, and are hence incompatible with DSi and DSi XL, although the former already has an alternative version made specifically for the Nintendo DSi and later consoles). Although Nintendo DSi and Nintendo DSi XL lack the SLOT-2, some Nintendo DS titles released after the Nintendo DSi's launch do support the Rumble Pak accessory, likely due to the fact the Nintendo DS Lite console was sold concurrently with the Nintendo DSi and Nintendo DSi XL.
