Nintendo has updated the Wii and DSi shops with a mixture of retro-themed downloadables covering WiiWare, DSiWare and Virtual Console.
First of all, Wii owners can get their 'motes on Megadrive game Galaxy Force II for 800 Wii Points (GBP 6 / EUR 8 approx), providing hours, if not minutes of Space Harrier style fun.
But that's not all, because you can also invest 600 Wii Points (GBP 4.20 / EUR 6 approx) in Bit.Trip Beat, a new WiiWare game where you "bounce beats in time with the 8-bit style soundtrack". There's four-player support and a robust, "retro-style" difficulty level.
Elsewhere, DSi owners can choose between a pair of oldie spin-offs - A Little Bit of... Dr. Mario and A Little Big of... Magic Made Fun: Funny Face. The former is 500 DSi Points and the latter 200.
As you have correctly guessed, the former is similar to Dr. Mario & Germ Buster for WiiWare, while the latter is a snippet of DS title Magic Made Fun, with a bonus vanishing card magic trick.
