You can probably find "A la Poursuite de Carmen Sandiego dans le Monde," for sale somewhere on Ebay - I noticed that there are quite a few english copies up for sale there, so if you dig deep enough I'm sure you'll find yourself a copy.
Of course, it's already been mentioned that the game is ESA protected, so no download for you good Sir
I loved this game - many a rainy afternoon was spent in the school library playing it. *sigh* Good times
(By the way, has anybody seen the animated television series that was based on Carmen Sandiego and her V.I.L.E henchmen?)
