If you buy the new collection (around $15) you can have the first three games and have it automatically setup in DOSBox for you.

I dont want anything prior to PQ4 nor the swat series this is the game I love! I just cant get it to work 🙁

if anyone can help please pm me.
thnx

Read my 60 Seconds Guide to DOSBox (and don't just read it - follow it too).

If that doesn't help, come back with details on how you mounted your C and D drives, how you did the install, how you configured sound, music etc.

Reading the aptly named README file will be a good idea too.
