I have made an installer for Phantasmagoria that makes use of Endroz's UniSCI tool to completely install to the HDD for CD-less play. Unlike the German installer it installs the DOS version of the game and automatically sets the game up to run in DOSBox. This makes the game playable on 64 bit Windows. It also addresses a fatal crash that the German Windows installer has when entering the shop at the beginning of chapter two.
