M3 help, please

Hey peeps, it's me again, SCK, the person who asked for information about R4 he, or should I say I, was going to buy.
I brought it, it's awesome, I am very thankful for all of your help, and this is the case this time:
The webpage I brought the R4 of mine from has now gotten M3s. ("M3 DS Real Perfect Bundle")
And well, I believe GBA data works on it, and that is the reason I would like to buy this M3 thing.
Now I have severeal guestions before I will buy a thing:

1. Does the device work on Vista? It's drag and drop (I've heard), so I believe it does, but just to make sure.
2. How does the GBA data supporting work? Do I just drag and drop the GBA roms to the chip or...?
3. Could you give me some other explonation about how the thing is different that R4, too, please?

Thanks.

 

I see, I see.
Well, as for the model, the page says that GBA data and NDS data both work on the thing.
As for your answer it still left me a lil bit confused. Can I just simply put GBA roms in to the microSD card and they will work, just like the NDS roms?
Oh and as a loopy idiot I forgot the guestion that is the most important of all for me.
You see, I have this really kickass savefile in my R4, and I was wondering, if I move the rom of that very game and the save file into the M3, will they still work? I am starting to think I should not bother buying m3 though.

 

Only GBA ds.gba or .gba ROMs can be run on a Slot 2 flashcart, so if you comes with a device that plugs into a DS's Slot 2, it should be able to run GBA compatible games. You should be able to use the R4 save with the M3 without doing anything, since they're virtually nearly the same.

 

I see, I see. Well, I think I will just stick to my good old R4, since I can always just play GBA games on my computer, using emulators.
Thanks for all the fast answering once again

 

If you want GBA, you could get an EFA linker or something...
