Shiny Legendary Trio - Wifi Event

[Locked Achievement]

Im staying at my grans house this weekend - she has wi-fi there. Since Raikou's event ends at saturday evening I may be also able to get Entei, too!

Damn. Unfortunately, my Grans wireless doesn't work with DS Lite. I could tap into her neighbours wifi, but I couldn't onto their wi-fi recieving the initial connection. DAMNIT!!!

Does the event work with any old shiny entei, raikou or suicune? because I have a shiny Suicune, that wasn't recieved via event, but does it have to be recieved from an event or will my suicune work?
