View source for Dual-slot mode

{{incomplete|needs=Pokémon Mystery Dungeon: Rescue Team information}}
'''Dual-slot mode''' (Japanese: '''ダブルスロット''' ''Double-Slot''), often called the '''Dongle method''', is one of the many ways that players of {{game2|Diamond|Pearl|Platinum}} can obtain Pokémon that are outside of the [[List of Pokémon by Sinnoh Pokédex number|Sinnoh Pokédex]], especially Pokémon that are exclusive to other regions, by using the [[GBA]] games of the series as {{wp|dongle}}s for the DS games. However, due to the removal of the GBA slot, dual-slot mode is not available if using a [[Nintendo DSi]] or a [[Nintendo 3DS]]. 

The majority of Pokémon that can be obtained in this way are in some way [[version-exclusive Pokémon]] to one of the [[Generation III]] games. With one of the five Game Boy Advance games inserted into the GBA slot of a [[Nintendo DS]] while playing either Diamond or Pearl, players will be able to find Pokémon not otherwise available in [[Generation IV]] in certain areas of [[Sinnoh]], but only after they have unlocked the ability to use [[Pal Park]] as well. One does not need to have the game in their GBA slot the whole time; one just needs to have it in at the main screen, at which time one can simply take the cartridge out, as long as one doesn't turn the power off before catching the Pokémon.

Unlike [[Pal Park]], dual-slot mode is not language locked; any language Generation III game can be inserted in the bottom slot for any language Generation IV game. For example, a Japanese FireRed can activate wild Elekid in the [[Valley Windworks]] in an English Diamond, while an English Emerald can activate wild Teddiursa on {{rt|211|Sinnoh}} in a Japanese Platinum. 

All of these Pokémon have an 8% chance of appearing in the listed area when the correct GBA game is inserted, except in areas where two appear at once for the same game (the rate is then 4% for each).

[[Pokémon Dream Radar]] has a similar feature that allows players to catch a Generation IV [[version mascot]] with its Hidden Ability in extensions unlocked by putting the Game Card of the corresponding game into the slot on the Nintendo 3DS.
