By the way. When I use DosBox, all that happens is the first line in dos appear (The one who tells you the version of the game and the creator) and then it just comes to a halt. I can wait forever, but nothing happens.

No surprises there I'm afraid Tom Henrik. Transport Tycoon does not work in XP or DOSBox. You will have to wait until DOSBox becomes compatible with Transport Tycoon or play it on a DOS/Win9x system.
The DOSBox people do claim that TT runs on the current CVS build for DOSBox. If true the next release should be able to run TT.

Wait?!
 

Well....

This surely puts a damper on my spirit today. I really wanted to play TT again.

Do you perhaps know when the next release of DOSBox is available?

The usual answer for such a question would be, "when it's done". DOSBox is a project worked on by volunteers and enthusiasts (just like Abandonia). They work on it as much as possible but real life invariably gets in the way. That said, it has been less then three months since the last release. I would not expect a new version to be released for some time yet. You could try and get the cvs build version that supports TT. Ask around at the DOSBox forums how to get a hold of that one. http://vogons.zetafleet.com/index.php?c=7

Thanks. I'll give it a try :D

You can download TTDX elsewhere on the internet, it works on XP though it runs in a window (can't figure out how to make it run normally though it running in a window may be why it does not crash). To find it just search google for "tranport tycoon"+abandonware.

To run it in fullscreen, you need your desktop resolution set to 640x480 and I don't think you can do that under Windows XP manually.

uhm, yes you can...
goto desktop properties --> settings
and click advanced
then goto adapter and click "List all modes"
I think that should of helped you ;)

Hmm, yes! Thanks! :D What a fool I am to not have found this earlier...

You can also change the resollution with regedit.
