Managed to get it working, you need to install from windows, patch the game with patches 1.03 and 1.05 and then run from within dosbox SETUP.EXE /V3 to setup the game and RIPPER.EXE /V3 to run the game.

More detailed instructions are on my signature link.
Good luck!

Wow!! That did the trick! It seems to play pretty well although I notice that video and audio will occasionally stop and then resume. Here is my dosbox.conf below:

# fullscreen -- Start dosbox directly in fullscreen.
# fulldouble -- Use double buffering in fullscreen.
# fullresolution -- What resolution to use for fullscreen: original or fixed size (e.g. 1024x768).
# windowresolution -- Scale the window to this size IF the output device supports hardware scaling.
# output -- What to use for output: surface,overlay,opengl,openglnb,ddraw.
# autolock -- Mouse will automatically lock, if you click on the screen.
# sensitiviy -- Mouse sensitivity.
# waitonerror -- Wait before closing the console if dosbox has an error.
# priority -- Priority levels for dosbox: lowest,lower,normal,higher,highest.
# Second entry behind the comma is for when dosbox is not focused/minimized.

Any suggestions on how to improve the performance to prevent the occasional video and audio stopping? Thanks again.

I would recommend making an ISO image and mounting it instead of accessing the CDROM directly, this should help speed things up a bit more... (also make sure core=dynamic and cycles=auto).

After that it's just upgrading the comp 😉

Thanks for the advice. I tried your suggestion of modifying the dosbox.conf file and it actually slowed things down a little. As far as setting up image files for the disks, I did that, but the program specifically asks for a disk from the D: drive (CD-ROM). Is there a way to fool the program into thinking a virtual drive containing the image file of the disks is drive D?

imgmount d nameofimage -t iso ?

My disks are located in C:\Ripper, so I tried the following command (deleting the "mount D D:\ -t cdrom -usecd 0 -ioctl" command):

imgmount Z C:\Ripper\RIPPER1.iso -t iso

It did not work. It still asks for a disk in the D drive. I must not be using the right set of commands. Can you please help me out?

Z ??

I figured out how to mount the image files of the 6 disks into the dosbox.conf file and it worked. Not only that, but there was no more stuttering. Thanks for your help. One question though, I have set the dosbox.conf file to read:

mount c c:\

When I do this (using v 0.65), I get a warning which says "Mounting C:\ is not recommended. Please mount a (sub)directory next time."

What is the rationale for this warning? When I change it to read:

mount c c:\Ripper

The warning goes away, but my sound card no longer works. What is happening here? How might I correct this?

Various, its not always the best idea to mount your root drive "just in case". Its just to cover asses really, as some dos games are grabby.

mount c c:\Ripper

The sound card doesn't work because the config file is pointing to a directory that doesn't exist. Rerun the setup with the above mounted and it should solve it.

Thanks for the advice. It works great now.
