When fighting game fans got their hands on the first copies of Street Fighter Anniversary Collection, which released this week in Japan only, they made an interesting discovery--the game booted up in all Xbox hardware, regardless of region. It even played over Xbox Live with no compatibility issues. This came as great news to Street Fighter fans in the US who did not want to wait for the game's planned February release.

This morning, Capcom pulled the game from store shelves. While Capcom made no official statement on either the region coding or the recall, the publisher reportedly told Japanese retailers that it concerned a bug in the game.
