Supported by Grid Cartographer. Its Game Link feature assists in creating the game map. This is not an automap. From the Grid Cartographer's documentation. (note: this is not free software! the 'gamer' edition costs $19,99 and the 'professional' costs $49,99)

  1. 1.0 1.1 File/folder structure within the installation folder reflects the path(s) listed for DOS game data. For the GOG.com release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
