Luckily for people hoping to get their New Game+ on in SNK vs. CapcomCard Fighters DS, SNK is aware of the game-breaking bug. Unfortunately, they'll have to wait more than six weeks to get their hands on a repaired game.
SNK president Ben Herman released a statement on SNK Playmore's official message board stating that they have ordered new cartridges from Nintendo, which will take six weeks to receive. At that point, SNK will issue instructions for getting your game switched out for a corrected one. Be patient! Don't return the game to the store yet, because the replacement copy will have the same issue.
Anyone out there playing Card Fighters DS? We wonder how many people this issue affects. That's a nice way of saying we wonder how many people bought this game.
