Well that stinks, i doubt there's any flashcarts out there with it and if there are they're probably pricey
There wouldn't be much point, very few DS games used infrared functions.
You can however run the pokewalker emulator and transfer stuff to save files.

Not the same but the best you are gonna get without an actual Pokewalker and real DS Pokemon games compatible with it.
