I am no expert in PC work (and in english)  ::) but maybe someone can help me. I want to start lemmings 1 from cd. After setting sound and typ of PC (I tried all versions) the "start window" shows up, but I get no reaction on any key.   :'( How do I start Neon edition with XP.  :-? Details would be great because I am an absolute beginner. THANKS :)

What's the Neon edition?

It is a collecter box with lemmings, Lemmings Tribes 2, and a whole new world of lemmings
Maybe you can just explain me how to start lemmings with XP :-/

DOSBox will run all three of the Lemmings games.  The DOSBox manual should help you get DOSBox running, but if you need more specific help, just ask.
