I've seen official stickers under the shrinkwrap on sealed boxes (Falcon, Darkwing Duck, Ys III) and cases (Cotton), but never on internal packaging and they never looked anything like that. I also have a number of French-Canadian games and I've never seen stickers like that. And it looks like the game has a black tray rather than the standard white that came with most copies of Final Zone II. I'd say this copy has changed hands a few times and was "refurbished" somewhere along the way.
