Recieving local events on desmume?

[Diondelpino]

I was thinking of heading down to my local game store with my lap top to try and get the French/German/Italian/Spanish WC for the shiny Palkia & Giratina however I don't have physical cartridges of these games I only have them as rom's in Desmume would it be possible to receive them through desmume? If it is possible would I need access to some kind of wifi while I'm there? Thanking you in advance for your help!
