PAX Pokemon League

not sure if this will work for north america (or else) but..
"If you missed getting one when they were originally available, Canada’s YTV channel has now posted a code generator for Omega Ruby and Alpha Sapphire demo codes! You simply need to fill out the security CAPTCHA below to receive one. The code may be region-locked to English games, but it doesn’t hurt to try."

i tried the generator out and was able to generate a code(haven't redeemed it)

As a resident of the US, I can confirm that the code does work in the eShop! Now I can finally get my hands on the demo...

Thanks for sharing this!
