Theme Hospital (CorsixTH)

Game: Theme Hospital (DOS, 1997)

CorsixTH: an open-source reimplementation of Theme Hospital, Bullfrog’s hospital management sim, that loads the graphics, sounds, levels, and movies from the original game’s files. It’s written in C++ and Lua, which holds most of the game logic, and runs on Windows, macOS, Linux, and BSD. According to the project, the whole campaign can be completed: every disease, object, and room is in, as are all events (emergencies, earthquakes, epidemics, VIP visits), the management windows, the music, and the movies. Still missing are multiplayer, the AI-run rival hospitals, the rats and their bonus level, vomit waves, and the level-won video and letter. It adds Full HD and 4K resolutions, zooming, UI scaling, subtitles, more than 20 languages, custom levels and campaigns with a built-in map editor, unlimited save files, your own music, building while paused, and rebindable hotkeys. Version 0.70.0 (July 10) added the official Russian Soft Club edition, 2x and 3x UI scaling, subtitles for the announcer, an option to turn off screen shake, MIDI devices, and an adviser message history; the latest release is 0.70.1 (August 28). It has rules for AI agents in its AGENTS.md file, and one of its more than 5,800 commits, from August and about the Windows ARM64 build, lists Copilot as a co-author.

You needThe files from your own copy of Theme Hospital, from the CD (the HOSP folder) or the GOG or EA release; on Linux they can be extracted from the GOG installer with innoextract. The demo, which the project offers on its website, works too, though it has a single level and lacks most management screens. Plus Windows, macOS, or Linux (as an AppImage, Flatpak, Snap, or distro packages).
