This is a list of Nintendo DS accessories. Accessories for the Nintendo DS often came in two forms: those that worked with Slot 1 as a regular DS cartridge, and those that worked in Slot 2 (for Game Boy Advance cartridges) known as a "DS Option Pak" when inserted in the DS or DS Lite systems main menu. When inserted, the GBA slot option on the DS menu will show the text "There is a DS Option Pak inserted", with the exception of any DS/GBA connectivity accessories such as Boktai Solar Sensors and Lunar Knights.
