European gamers may meet with a game-freezing glitch. Nintendo of Europe is offering an exchange. http://www.nintendoworldreport.com/newsArt.cfm?artid=14439 European gamers may want to avoid a certain gameplay situation in Super Paper Mario if they want to avoid a game freeze.
In Chapter 2-2, a character named Mimi will tell you to go and meet another character named Merlee. Enter that room, press the green switch, and a spiked ceiling will drop over Mario's head. If you flip to 3D, you can avoid the iron maiden and find a key. If you pick up the key, then use it to open the locked door near Mimi, you will avoid the glitch. However, should you fail to pick up the key, then talk to Mimi without it, your game will freeze.
Frozen Wiis will have to be restarted from your last save point, of course, meaning tedious redos. Just to be absolutely clear, this glitch is only present in the British, Spanish, and German versions of Super Paper Mario.
Nintendo of Europe is offering a free disk replacement to fix the error.
