The game selection menu has a "Maker" column. I don't think column is always correct. For instance, Last Story list its maker as Xseed games. Maybe the column should be renamed to "Developer/Publisher" or something along those lines?
It lists the publisher for all officially released software, but that doesn't apply to homebrew because they don't really have publishers. Also, GameCube games can put both the developer and publisher there if they want to. Star Fox Adventures is an example. I agree that Maker isn't a great name, but I'm not sure if any of the replacements are better.
Oh well, not a big deal. The "Maker" column can always be unchecked if it bothers anyone too much.
