It is in all cases a local connection so wireless while sitting next to each other without the Internet.
It's about which editons are compartiebel to fight and swap - or if only one of both goes.
and if that works if you take 2 3ds consoles or if it has to be 2 Nintendo ds / ds lite / dsi consoles
or whether it may be synonymous with the Nds titles a 3ds and ds lite?
- can fight hard gold / soulsiver with diamond / perl and swap?
-Can change hard gold / soulsive with black and white 1/2 and fight? (Of course only those who gave it in gen 4)
Can X / Y fight and trade with omega ruby / alpha sapphire?
Can sun and moon trade and fight with omega ruby / alpha sapphire?
The s / M with Us / Um as well as s / w and S2 / w2 kompartibel I know.
I would be happy about experiences and answers because the information in the internet are partly unclear. - Especially since it's all about whether the individual editions can fight.
Since you seem familiar with generations, you should realize that all games belonging to the same generation can interact with each other.
Consequently, editions that do not belong to the same generation can't interact.
So what I can say with swapping and fighting from the DS titles (that is not generally synonymous 3DS title I mean this just not) with swap and fighting is the console there does not matter (so synonymous that is a 3DS with eg Heart Gold and the others, an earlier DS with Soul Silver takes as far as I still know) including you can as in the example given Heart Gold and Soul Silver, Diamond, Perl and Platinum these would have to know my inter-compatible (not only with exchange I my fighting was just like that ).
Then there were still black & white 1 and 2 (I think these 4 went to each other only and some but you could not transfer from 2 to 1 as the animal forms of Boreos and the other 2 Whatever their name was like also the Legis in fused form). However, you could transfer to Pokémon X & Y which as far as I know by taking a 3DS with the 1st game of it and then you had to do something and select the ones over (sry but very long ago that I've done that only knows that it worked) and then sonen small catch mini game I mean and then you can pull on X & Y (I also do not know if you needed Pokémon Bank but believe I'm not 100% sure).
In the 3DS Games, Omega Ruby, Alpha Sapphire and also X & Y were all together compatible with combat and exchange. Then there was Sun & Moon and USonne and UMond these are also compatible with each other and with Pokémon Bank you can transfer there from the other 3DS Games Pokémon but you can't zrk on the front of Sun & Moon pack.
Was indeed a lot of information and I hope I could explain everything reasonably what you wanted to know and thus maybe even help you
