Thanks very much to everybody for the replies!
I should have been more specific about what the games are...
X-Com: Terror From The Deep (Special Edition to run in Windows 95)
The Longest Journey
There will be more to come but I guess I should take them one at a time whilst I'm playing them if there is no all-in-one solution.
Would VirtuaklPC work best for these games? If not, how should I go about it?
