Chavez II was released in the US and possibly some areas of Canada, at least in small quantities. The first copy of Chavez II I got was from a seller in Canada.
Really, I would group Super Copa and Chavez II in general North American releases anyways, as the packaging is the same. To exclude them based on some assumption that they didn't get sold in the US seems silly, because there is no way we can confirm this (unless somehow the ASC sales information becomes available).
