Hello there, I have read many of your guides here to find the flashcart that I should buy, but I am still confused cause there is some conflict between this forum and the seller's info. I have a nintendo DS (years old) and a newly bought german nintendo ds lite. I just want to play all pokemon versions (got all before emerald official cartiridges) but I also want to be able to trade-battle with my friends. What flashcart do you suggest for me? And please explain so I can understand. Thank you very much !
