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.

ok thanks i think it works now, i just have to configure it
thank you!

ok now the game works, but it's very slow... anyone know what's wrong?

dosbox version?

yes

WHICH dosbox version, more precisely?
And what OS, other system specs.....

oh i misunderstood you...dosbox 0.72

windows xp
733 mhz p3
but i totally forgot about the ram...where do i see how much it has??

A 733MHz P3 is waaay too slow to run Comanche 3 at a reasonable speed in DOSBox (it can hardly keep up with the game outside of DOSBox).

Before starting the game, try the following commands from the DOSBox prompt:

C:\> cycles max
C:\> core dynamic

well i did what you said and it works a little better but still not good...+ all the white lines and numbers(altitude, weapons,...) disappeared.. anyone? or is my pc really to slow for it..and what do you suggest in that case-i really wanna play a comanche game...

or is my pc really to slow for it..

At least if you want to use a full-pc emulator as dosbox.
Try vmware/virtualbox/vpc or whatever, good luck.

hey what about comanche gold? does it work without an emulator? i heard it's basically a re release of the comanche 3...

Try using just one of the commands then and see if the lines and numbers come back.

no they don't...

And if you don't type any of them?

no they're not there...

WHAT is not there?

white lines and numbers i guess

"Comanche Gold" works under XP, I played it a few months back. It even has more missions than "Comanche 3", so it's a good deal if you can find it.
