I'm trying to play a DOS game under DOSBox that uses long filenames. Here's the ISO as seen from macOS:


The ISO as imgmounted inside DOSBox:


I'm trying to start install.bat but I can't figure out how to do it. Based on the fact that it's a DOS game and it uses long filenames, I suspect that it was made for MS-DOS 7.

How do I install and run this game?

Edit: I noticed something odd. When I extract the ISO's folder structure and mount them, the directory structure looks normal. But for reasons beyond the scope of this post (the soundtrack being one of them), I need the actual ISO for the game to function properly.

Here's the directory listing if I just mount the extracted contents of the ISO with mount:

    Alternatively, you can type part of the filename (e.g. ins) and hit the TAB key on your keyboard. The command line interface should autocomplete the filename. It's possible the reason install6 doesn't work is because it should be INSTALL6 or install6.bat instead. The TAB key would fix mistakes like that.

    It almost looks like DOSBox is having issues with the files as the file extensions are being stripped.

  • I agree with Powerlord. What are the results of typing dir /x? Dec 30, 2016 at 13:30

    I agree with the comments. There's something wonky going on with how DOSBox sees the files. 7 characters + 3 character extensions should not need shortening in DOS. Also, the install.bat doesn't run, because DOS deosn't know it's a .bat thanks to the shortening.

    Yes, I am using imgmount. ins completes to INSTALL6, but when executing it I just get a Illegal command error.

This needs to be installed under Windows (autorun.exe). Start Windows, insert the CD / floppy, and then run autorun.exe (it may also be automatically run). Make sure you use Windows 95. It has support for long filenames. Don't use 3.11.

    The presence of an autorun.exe file doesn't mean that the program requires Windows, just that it will do something automatically (usually, launch the program or an installer) under Windows.

    A lot of games back then had more than one method of installing to cope with the DOS/Win3x/Win9x situation.
