Last week Nintendo made a massive news splash when it priced and dated its upcoming depth-of-field portable, the 3DS. Now, the House of Mario is doing what it does every Monday morning: bringing new titles to its download space.

First out of the gate this week is Jam City Rollergirls (1,000 Wii points, or $10) for WiiWare. From Frozen Codebase, the female-based roller derby title has players lacing up their blades and taking to the vicious world of the sport for some heavy action. Gamers can skate alongside real-world derby teams the Texecutioners, Dairyland Dolls, Brewcity Bruisers, Rat City Rollergirls, and Gotham Girls Roller Derby. Players can also create and customize a character and level her up, or choose a premade skater. The ladies bring the pain this week in Jam City Rollergirls.

Also out now on WiiWare are two new demos. The free samplers include a trial experience for Gamelion's puzzle platformer Furry Legends and a demo for Abylight's arcade fishing title Fish 'em All.

Switching to the nostalgic download hub, Nintendo added two new Capcom Virtual Console titles this week, the first of which is 1942 (800 Wii points, or $8). A vertically scrolling shoot-'em-up, the title has players controlling a biplane and tasks them with gunning down enemy fighters.

The other Capcom Virtual Console title out now is Black Tiger (800 Wii points, or $8). First released in 1987, the title has players controlling a mighty barbarian exploring regions infested with enemies he must defeat.

Nintendo added a quartet of new DSiWare titles this week, the first of which is Airport Mania: Non-Stop Flights (200 DSi points, or $2). From Lemon Games, the time-management title challenges players to coordinate a barrage of incoming flights without disruption for as long as possible.

Also out now for DSiWare is Rocks N' Rockets (500 DSi points, or $5). The title puts players behind the scope of a missile launcher and tasks them with shooting down incoming meteors to keep the city safe. The title boasts increasingly difficult meteors, 100 unique levels, and a variety of power-ups.

Gamers wishing to trade missiles for a shovel can download Digger Dan & Kaboom (500 DSi points, or $5) from the DSiWare storefront today. The title casts players as Digger Dan, an enthusiastic shoveler who searches through caves for valuable gems. The title also has players seeking out the whereabouts of Dan's gopher sidekick Kaboom, who has fallen asleep in the cave.

The last title out this week is Ante Up: Texas Hold 'em (500 DSi points, or $5). From MonkeyPaw Games, the portable gambling game has players stepping into the shoes of any of 12 playable characters and taking part in rounds of the popular card game. Characters include an undercover police officer, an aspiring actress, and 10 other "uncanny casino characters."
