CorsixTH (Theme Hospital for modern PCs)

What it is

Theme Hospital came out in 1997 for DOS and Windows 95. The original runs at 640×480 and needs DOSBox or compatibility tricks on modern systems.

CorsixTH is “a reimplementation of the 1997 Bullfrog business sim Theme Hospital. As well as faithfully recreating the original, CorsixTH adds support for modern operating systems (Windows, macOS, Linux and BSD), high resolutions and much more” (CorsixTH README). The engine is written in C++ and Lua, and loads the original game’s graphics, sounds, levels and videos from your copy.

The project began around 2009; the GitHub repository dates from 2013 and is updated regularly.

Current status

• Status: Working. The README says “you can complete the full campaign without issue”.
• Latest release: 0.70.1, 28 August 2026, with a Windows installer and zip, a macOS disk image and a Linux AppImage.
• What 0.70 added: support for the Russian Soft Club edition, 2x and 3x UI scaling for 4K screens, announcer subtitles and an option to turn off screen shake, MIDI device support, new cheats, pausable movies and an adviser message history (Ctrl+H) (0.70.0 notes).
• Other channels: Flathub, Snapcraft and packages for many Linux and BSD distributions.
• Android: a third-party port, also for Chromebooks, linked from the project wiki.

What works and what is missing

From the README, the original features are all there: the single-player campaign, every disease, room and object, all events (emergencies, earthquakes, epidemics, VIP visits), the management windows, the jukebox, videos and cheats.

Still missing or incomplete:

• multiplayer and LAN play;
• AI rival hospitals;
• rats (the holes are there) and the bonus rat level;
• vomit waves and the level-win video and letter;
• some patient graphics the original never completed (pregnancy, Alien DNA, female fractured bones), which can glitch if you force them to spawn.

What you need

• The HOSP folder from your own Theme Hospital: from the original CD, or a download from GOG or EA. It contains folders such as Data, QData and Levels. A default GOG install on Windows is in C:\Program Files\GOG.com\Theme Hospital.
• Or the free demo, linked from the Getting Started page, if you only want to try it. It has one level and lacks most management screens.
• A Windows, Mac or Linux computer. Linux users can unpack the GOG installer with innoextract.

How setup works (overview)

What it adds

• Full HD and 4K resolutions, zoom and UI scaling.
• Custom levels and campaigns, and a built-in map editor.
• Over 20 languages and subtitles.
• Unlimited save slots and your own music in the jukebox.
• Building rooms while paused, removing destroyed rooms for a fee, a machine menu and fully rebindable hotkeys.
• Improved game logic that fixes original bugs.

Common problems

• It keeps asking for the game data: point CorsixTH at the folder that directly contains Data, QData and Levels, not its parent.
• Tiny text on a 4K screen: update to 0.70 or later and choose 2x or 3x UI scaling.
• Missing music: CorsixTH can play the original MIDI tracks or your own MP3s; since 0.70 it finds music folders in its own directories automatically.
