Nintendo offer up trial servings of Nintendogs and Jump Super Stars from hundreds of download stations across Japan...

Free demos of the two top titles have been made available to download via wi-fi from special access points in 326 locations in Japan, including some of the country's largest railway stations.

The demos are stored in the DS unit's memory until the power is switched off or the battery runs out. But if that happens, the game can be downloaded for free again!

No news on a similar scheme outside Japan, but its something Nintendo of Europe could consider!
