This fools the game's startup check into seeing the "D:" drive as a valid CD source. A Modern Alternative: CorsixTH
Use the following command (replace the path with your actual folder): imgmount d "C:\Games\ThemeHospital\TH_CD.iso" -t iso Then, mount your C drive as usual and run HOSP.EXE . 2. The "HOSP.CFG" Edit (Best for extracted files)
Example: CD_PATH=C:\THOSP\ (Note: This must match the drive letter you mounted in DOSBox). 3. The "Fake CD" Mount
If you have all the game files in a folder but no ISO, the game is looking for the CD path in its configuration file. Find the file in your Theme Hospital folder. Open it with Notepad. Look for the line starting with INSTALL_PATH= and CD_PATH= .
Point the CD_PATH to the folder where your game files (specifically the DATA and LAY folders) are located.
If the game still insists on a CD, you can mount your game folder as a CD-ROM drive: In DOSBox, type: mount d "C:\Games\ThemeHospital" -t cdrom
If you have a disc image of the game, you can trick DOSBox into thinking it’s a physical drive.
