I own US and German Ruby and Sapphire games. When I connect the US games to Colosseum Bonus Disc on my Gamecube I can download Jirachi. But the German games don't work. I get an error. So, obvously the language is checked.
Now, when I would buy the UK version of Colosseum will it work with the US games? Or do I need the US version of Colosseum?
