DOSbox software for running Pyrosim in Windows 7, 8, or 10

Here are the instructions required to make Pyrosim run under Windows 7, 8, or 10.

The DOS capabilities of Windows 7 were broken by Microsoft. However, there is a free utility that provides an alternative that works well. This requires going to and downloading the free DOS compatibility software by selecting 'Downloads' then 'Windows'. This takes you to the direct link below.

Once the DOSbox software has been installed, there is a simple command that needs to be typed in to tell DOSbox to run from your C: drive:

> mount c c:\ (You can safely ignore the warning that is given)
> c:
> cd Pyrosim
> Pyrosim

This can be automated (by putting these commands into a configuration file) so that you just click on a Pyrosim icon and everything works directly. This is how I have it on my 64-bit Windows 10 machine.

If you need to create a shortcut on your desktop (for example), this can be done by right-clicking on the desktop and selecting New / Shortcut. Then you right click on the shortcut to get to the Properties, described below.

There is a file, either supplied in the c:\Pyrosim folder or downloadable here, called dosbox-Pyrosim.conf that can be used for this purpose. (Please save this file in c:\Pyrosim if you don't already have it there.) To use this, I have an icon on my taskbar (or on the Desktop) that points to the DOSbox program and has the following properties. (Please note that the 'Target:' section should all appear on the same line when typed in.)

"C:\Program Files (x86)\DOSBox-0.74-3\DOSBox.exe" -exit -conf "C:\Pyrosim\dosbox-Pyrosim.conf" -noconsole

Start in:
"C:\Program Files (x86)\DOSBox-0.74-3"

The contents of the configuration file are standard except for the last five lines or so. You should be able to view and edit the file using Notepad.

I hope this information helps you to get started. The DOSbox documentation should explain more generally how to run DOS programs under Windows 7, 8, or 10.
