Another emulator for gba roms with multi player support

how can i make a GBA link using an emulator.
I need it to transfer some data from a game to another.

I was wondering what Flash device would be best for running the game boy emulator and GBA games on the DS. I read the section but it looks like there where many choice, was just looking for narrower recommendations.

I am interested in getting a flash cart for my game boy advance but
cant work out which one would be the best for me. As well as playing
.gba roms I would like one that is compatible with .gb and .gbc roms
so I can use them on my original game boy without the use of an
emulator. If you know of any that can do this could you please let me
know.
