Convert GBA to NDS?

Would it be possible to convert a .gba archive to a .nds archive in such a way that it is playable on any flash cart? Yes I did research and I came across something called NDStation, which practically does the thing, but with one big downside: it doesn't work. So does anyone know if it's possible to get something like that to work? (or, if you're able to and have the time for it, make something like that?)

What would you like to see in Pokémon heart gold and soul silver?

Hey everyone, this is a thread where you can post and discuss what you'd like to see in Pokémon heart gold and soul silver.
For example, I'd like to see the odd egg (50% chance of shiny!), the mystery gift as it was in g/s/c (so you can get dolls and stuff) and Kurt's balls (which probably aren't going to be in it because of compatibility problems with d/p/p)
Have fun discussing!
