DeadSkullzJr Posted January 13, 2022 Share Posted January 13, 2022 (edited) Hello everyone, today I bring you something new to the table. Years ago I wasn't fortunate enough to own every Pokemon game for the Game Boy Advance, it wasn't until years later when I could finally get my hands on more copies of the games, the drawback however is the absurd price tags that many sellers throw these respective titles up for. At one point I looked down at the copies I owned and wondered if I could somehow replicate or utilize dual-slot mode in the game, without having to require these game cartridges. With enough research and some tinkering, I can now happily say that it is now possible to utilize dual-slot mode in Pokemon - Diamond, Pearl, and Platinum Version without requiring the respective Game Boy Advance titles. Pros: - Allows the ability to participate in Dual-Slot Mode exclusive Pokemon encounters. - Able to be switched on the fly without having to reboot the game console. - Allows the ability to obtain Dual-Slot Mode exclusive items. - Can be used on any Nintendo DS/3DS system without requiring the Game Boy Advance game cartridges or Slot-2. Cons: - Does not enable the ability to migrate Pokemon. Why doesn't this allow the ability to migrate Pokemon? Answer: Well, it should be pretty obvious, but the reason being is because you cannot mimic an entire game cartridge with save data using cheat codes.

Diamond and Pearl version doesn’t seem to work at all though. I just tested, they are working as intended for me, the best way to know for certain is to talk to the woman in the Pal Park on the second floor on the right, she gives backdrops depending on the Game Boy Advance title in slot-2. If she gives you stuff then the code is working, as will the encounters, you just have to deal with the scarce encounter chances.

DeadSkullzJr Posted June 30, 2023 Author Share Posted June 30, 2023 Included variants for HeartGold and SoulSilver. Meant to do this some time ago but forgot. These titles don't have exclusive wild encounters, however you can still get contest related backdrops and accessories from the woman in Pal Park like you could in the previous titles. 1 Link to comment Share on other sites More sharing options...
