VDMS:
http://sourceforge.net/projects/vdmsound/
But I wouldn't set my hopes too high on VDMS, it's mainly a sound solution, not an emulator.(And it's discontinued).
Other possible solution, IF RR is a w3.x game: setup W3.x in dosbox 0.72, works pretty swell.

Looks as a whole hassle, but it's pretty easy in fact, and runs extremely good.
Also: look once again in your game folder if there isn't a dos launcher, many of those older games had a dos and a win launcher, ya never know .....
If you can put the game on zshare or so and PM me the link, I could try it in VPC also.(W98-W3.11-and a lot of other OS)
