Have you tried renaming the .hpf file extensions to .iso?

Does the GOG release use DOSBox to run the game on Windows? If it does have you checked their dosbox configuration/mounts/etc...

Renaming the file to "iso" doesn´t solve the problem.

But now i was able to mount the directory at least....
Problem is, the game doesn´t start and delievers no error message....

GOG does just the obvious things:

mount C ".."
MOUNT d "..\data" -t cdrom
cls
c:
express.exe
exit

Okay, so why aren't you doing the same thing..?

Evidently the game loads its data directly from these .HPF files, which might not be standard CD images at all.

When you say "mount the complete data-folder", what exactly are you mounting?

I did the same thing as mentioned in the GOG config....

the game is stored in a folder named "TLE", the subfolder is named "DATA".

I did: mount d "/home/pi/RetroPie/roms/pc/TLE/DATA" -t cdrom

The mounting worked. And i used exactly the dosbox config values, used by gog.
But the game doesn´t start....

To be clear, what are you mounting as drive C?

Drive C: /home/pi/RetroPie/roms/pc

It´s my games folder.

I than make an startup script which changes to c:/tlw and executes the game file express.exe

I did it that way with 60+ games

If that was supposed to work, then the GOG script would include a "cd tlw" command.

Evidently in this case you need to mount /home/pi/RetroPie/roms/pc/TLE (presumably the directory that includes express.exe) as drive C. This is definitely not something that would normally be done, but that appears to be the way the game has been configured.

This doesn´t work either.... same problem.
Maybe the problem is that the device is a retropie (=Raspberry Pi) and the game is one of the last dos games (1997!)....
Maybe the graphic power of this little box isn´t capable of playing the game. It has (for that time) a pretty good graphic.

Then i have to play it on a windows machine. Not what i wanted but.... the game was just 1,30 € in the sale at gog 😉

That is very unlikely. At worst, it would only work slowly. If it works on Windows, it should work under Linux on your Pi, unless somehow you're using a very different version of DOSBox.

What exactly happens when you try to run the game, anyway? Perhaps you copied the files incorrectly?

When i try to run the game, the screen gets black, an mouse pointer (not the normal one) is visible for a very short time, and the game crashes to dos, without any message.
Thats because i thought about a graphics issue like vesa driver or something.

No, DOSBox does not work that way. I'm pretty sure this is some kind of mounting issue. I'm wondering what exactly your "startup script" does.

If you are using DOSBox 0.74 then try installing and running with a build of current source. Some (perhaps not all) versions of The Last Express are PC/Mac hybrid cdroms that have an issue that is fixed in SVN.

The .HPF files are just the game data files that are on the CDs, not disc images. GOG is just dumping the contents of the CDs into a data subdirectory and mount that as the CD.
