‘HeartGold’ and ‘SoulSilver’ Compatibility

In case there was any doubt, HeartGold and SoulSilver will still feature the Pal Park or a similar feature. Of course, such a feature will only be usable if the games are inserted into a Nintendo DS or DS Lite since the Nintendo DSi does not have a GBA slot to connect to the GBA games. According to the official Nintendo website…

• Pokemon HeartGold and SoulSilver are remakes of the Game Boy Pokemon Gold and Pokemon Silver (doy).
• HeartGold and SoulSilver have differences in “types of Pokemon that appear” and “Pokemon appearance percentages.”
• Communicates with “HeartGold,” “SoulSilver,” “Diamond,” “Pearl,” “Platinum,” “Pokemon Battle Revolution,” also using the double slot feature with “Ruby,” “Sapphire,” “Emerald,” “FireRed,” and “LeafGreen.” (Communication using the double slot feature is only supported by the Nintendo DS and Nintendo DS Lite.)
• PokeWalker only supported by “HeartGold” and “SoulSilver.”
• Can not communicate with Game Boy and Game Cube Pokemon series games. Also, not supported by Wii Ware “My Pokemon Ranch (including Platinum version).”
