Nintendo is celebrating sports, gambling, and wildlife conservation with today's additions to the online Wii Virtual Console. All three games will be available at 9 a.m. PST/12 p.m. EST.

Double Dribble, Konami's much-loved NES basketball simulation for one or two players, arrives on the download service at 500 Wii Points ($5). Ecco Jr., Sega's child-friendly Genesis expose on the antics of young dolphins, sells for 800 Wii Points ($8).

Vegas Stakes, meanwhile, comes from Kirby developer HAL Laboratory. The Super Nintendo title offers blackjack, slots, poker, craps, and roulette for up to four players, along with the occasional encounter with another gambler, which, depending on your actions, can end in profit, loss, or everyone thinking you're a jerk. To stay on the table, you'll need to chip in 800 Wii Points ($8).
