Nintendo has officially confirmed the line-up for its second run of Famicom Mini titles - NES titles ported to the Game Boy Advance and manufactured in limited quantities to help commemorate the NES console's 20th anniversary this year. The second run of titles consists of Mario Brothers, Clu Clu Land, Balloon Fight, Wrecking Crew, Dr. Mario, Dig Dug, Adventure Island, Makaimura (Ghosts n' Goblins), Twinbee (Stinger), and Mystical Ninja Goemon.
All ten games will debut in Japan on May 21st, at 2,000 yen (15 or so) per unit. Nintendo has also warned that it will cease production of the original ten titles on May 21st, so expect supplies to dwindle very soon thereafter. Not to worry though, because Nintendo of America still plans to release the original ten games in the States this June 7th as the Classic NES Series, along with a very smartly dressed NES-style Game Boy Advance SP. Presumably these ten latest titles will make the transition to the West later in the year.
Nintendo of Europe has yet to announce plans for the Classic NES Series, but thanks to the lack of region protection on the GBA format you can always import them relatively cheaply from either Japan or the States, your best bets probably being TRONIX, NCSX or Lik-Sang.
