Notes

↑ ^1.0 ^1.1 ^1.2 ^1.3 ^1.4 ^1.5 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).
↑ ^2.0 ^2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/240180/ in addition to or instead of this directory. The app ID (240180) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.
