The game uses DOSBox ? Is there a mistake on the product page or what ? We're speaking of a game that's not even out yet, and for the record, we're in 2019...

Yes, it is a mistake and the game doesn't use this.

Okay, I notice the mistake has been corrected. I had started wondering if DOSBox was providing some sort of library in addition to the well-known emulator...
