1. Open the Chasm the Rift Original sub folder in your Chasm the Rift game folder and you will find the files CHASMPR.CUE and CHASMPR.BIN.

2. Use Dosbox-Staging to imgmount the CUE file and install the game to your mounted C drive.

For example: Note: Make sure you replace path\to\CHASMPR.CUE with the relevant location in your system. If your path has any spaces in it, you must enclose the path with double quotation marks or else the imgmount will not work.

3. In Dosbox-Staging's command prompt, change to your D drive by typing d: and pressing Enter.

4. Type dossetup, press Enter, and follow the prompt to install the game.

5. After the game is successfully installed, apply ALL fixes as stated in the link below:

When creating the .bat file (which is case insensitive), I recommend setting cpu_cycles_protected = 250000.

Also, every time before you start Chasm: The Rift in Dosbox-Staging, you must imgmount the CUE file so that the game music plays. If you do not do this, the game will not have any music.
