Are you having problems playing it on your Compaq Deskpro?
You probably need the version 1.3 patch that fixes VESA 2.0 incompatibility. The 1.5 patch does not include the contents of the 1.3 patch and won't help with VESA problems, so you need both.

(if anyone is interested in trying it on XP).
You can get the 1.3 patch from the web archive of the JA website -- direct link ***here***
The 1.5 patch is also available at the web archive -- direct link ***here***
I include that link since patches-scrolls doesn't seem to have the Ripper patches in their latest iteration.
You can read about what JustAdventure's "JAVE" originally had to say about Ripper ***here***
These look like the same patches, going by file sizehttps://archive.org/details/ripperpatch
