Hi,
I bought the game, and I'm currently running it under Windows XP, on a VirtualBox virtual machine. The game is unusually slow, I understand that VirtualBox does not have (yet) proper graphics aceleration, buth as this game is quite old and does not use any fancy 3D graphics, it should run fine. Age of Empires, for example, runs fine (except some minor corruption, nothing very serious).
I was wondering if anyone has any tips or recomendation for running this or other technically similar (DOS) games under Windows XP + VirtualBox.
Specs:
Windows XP + SP2
VirtualBox 2.1.2
Host OS: Fedora 10 x64
CPU: C2D T8300
RAM 4GB, 1.5GB assigned to VM
Graphics Card: ATI Radeon HD 2600 (correctly instaled under Linux, fglrx drivers)
although I don't think the hardware is an issue.

Not yet, although that would be my next step, I haven't had the time to look into it.
That would probably solve it, yeah. And without having to run the VM, which is nice.
I'll check it and report soon, thanks.

That did the trick! And since GOG's version uses DOSbox, I just had to take the included configuration file and tweak it a bit.
Now it's working fine, better than under VirtualBox :)

Well, I haven't really had the time to play, so last time I tried it (under DOSbox, not the virtual machine), I only made sure it would start, I didn't really play. All seemd fine, until I got past the menus and all that, and started playing the actual game.
What happens is that very shortly after game start, my company goes bankrupt! Even without doing anything, without spending any money whatsoever, the money goes all away! :/
So, has anyone managed to run this game properly under Linux, with DOSbox or under a virtual machine? I realise that this is not a supported platform, but on the other hand the game wasn't designed to run under Windows XP/Vista eiter!
Anyways, if someone has any tips, I'll be glad to hear them.

which version of dosbox are using on linux ?
and did you execute the same lines as in the configuration file of GOG ?

Lastest version at that time, 0.72 - 64bits.
The config file is the same that GOG used, I only changed the paths.

sounds like a copy protection thing.
Will try my version as I have 0.72 +64 bit as well
works fine.
I changed the [autoexec] of dosboxCapPlus.conf
to
mount C "."
imgmount d "CapPlus.gog" -t iso -fs iso
c:
cap.bat

Weird, this is exactly what I have, except the 'mount C "."' part, I used a full path instead of ".". I'll check if it has any influence. I've never used DOSbox before, but I think I saw somewhere some reference to speeding the emulation up/down, maybe I'll try that. Maybe the game is being emulated too fast?
Unfortunatelly I don't have much time play, I guess I'll just leave it like that until I can spend some more time with it.
Thank you for your help! :)

Try this: Navigate to the game install directory, find the file "dosboxCapPlus.conf", open it in notepad/whatever, find the line that says "core=auto" and change it to "core=normal".
That fixed some very strange bugs I was getting with the tutorial.

I haven't had the time to try this, but I guess this (or something similar) should do it, thanks for the tip!

I'm having the same problem with Capitalism 2. Does anyone know how to fix this issue with that game?

Be careful!
The config file originally says "capplus.gog" but remember Linux is CASEsensitive, so... one of those details I only looked after many other extremely complicated assumptions, haha.

Worked great for me after that.
