This week's Nintendo eShop update has gone live and while it's not bursting at the seams with new content, there's enough for each Nintendo platform to go around.

On the Wii U, a new demo for Rayman Legends has released that comes with a series of challenges that players can compete in against friends online.  The demo is free and enables you to take on various stages while outscoring your rivals.  The demo was initially offered after Ubisoft delayed the release of Rayman from its proposed February release date.

Over on the 3DS, players can check out the NES classic Mega Man 4 ($4.99), while also checking out G-Style's strategic (yet humorous) Crazy Construction ($4.99).

Meanwhile, the original Wii is getting some love with another Neo-Geo classic Sengoku.  It features two player hack and slash action, all for a fairly good price of 900 Wii points ($9).

Finally, DSiWare fans can check out Circle Entertainment's action-packed Color Commando, though pricing hasn't been confirmed at this time.

Happy downloading!
