I'm running DOSBox 0.73 in Ubuntu, and trying to get the game The Last Express to work. The game is on three CDs (isos), and the first CD worked fine, allowing me to install and play the first part of the game. Mounting the remaining two CDs will not work correctly however.

These CDs contain a big game data file each, which for some reason is displayed twice in the directory listing, one with the correct size (~690MB), and one of only 2,238 bytes. This small file is listed first, and I therefore assume it overrides the real file. At least that is the file that is copied when using the copy command, and the game complains about not being able to read the file.

As for the content of the small file, it's not just a small bit from the beginning og the real file. The first seven bytes are 00 00 01 00 00 00 08. There are some more or less recognizable strings in the file: "CD2.hpf" (the filename), "TEXTmdos", "ICN#", "icl8", "icl4", "ics#".

Also, mounting the iso natively works as expected, so it looks like this might be a bug in imgmount and not an error in the image.

So, halp please?
