But doesn't the NDS Adapter Plus still require the use of a soldered game cart? Or was that just the regular NDS Adapter that required that?

Yes, I have an M3DS Real. It's a slot 1 card, so I'm not sure how well it would work for backing up/restoring saves. But I'll try anything you want me to, within my capabilities. (I'm a long time IT person, so the capabilities are not insignificant) I've been hanging out in the irc a lot lately too....

It might do something along the lines of the friend code. Such as the same game cart giving different results depending on the DS it's in. Suppose that's something to try. Ihave 2 of each game with my kids copies included, but I have no way to backup/clone anything since the ARDSi isn't working with the HGSS carts.

One thing I'd like to know more about is if there's any kind of unique pokewalker-ID stored in the save to tie one game to one walker. (Seems the identification information is stored on the pokewalker side; my guess it it's just the ID, SID, or both of the current player.)

I had started on HG with an AR code to setup my trainer. I had then caught a pokemon and sent it to the pokewalker. Later on I had brought it back and then decided to reset my game (didn't want to use cheats). I used the same code though to establish my trainer after restarting the game (in case I change my mind later about the cheats) and when I tried to send a newly caught pokemon to the walker, it said it could not complete the connection. So there is something being stored besides the ID and SID since those were identical.

Because IR Enabled games such as HG/SS store the save files differently. Hopefully it's just a matter of Datel writing an update for the ARDSi to be able to handle the saves.

Both for sure. Easiest way to catch em all.
