Returning to the topic of regional differences for a moment, Miracle Mask has some interesting differences between the US and EU versions.
First, what is known as the Nautilus Chamber of Akbadain in the US version is called the Infinite Vault of Akbadain in the EU version.
Bronev's dialogue is also different, which somewhat alters his depiction between versions:
US: You still haven't found it, you incompetent fool.
EU: I take it you still haven't found it?
US: Oh well, as long as you're sorry, I suppose everything is fine. Get the mask.
EU: Apologies do not produce results. Get the mask. Is that clear?
US: It is perfect weather for a day of world domination. Trespassers! This site is now controlled by Targent.
EU: Trespassers! This site is now controlled by Targent, and we can't have you two blabbing about what you've seen.
US: Descole. Oh, Descole... tsktsktsk
EU: Descole. Oh, Descole...
