Heroes of Might and Magic II

The latest Humble Bundle comes with HOMM2 Gold in the pay-what-you-want group. While it's for Windows only, the installer works in Wine flawlessly.
When it's started I noticed the game actually runs in DosBox, which sounds somewhat silly - to run a game inside a DOS emulator which runs in a Windows emulator :-)
The natural instinct lead me to try to remove the unnecessary levels.
I used lnk-parser to find out what the HOMM2 Desktop link was actually doing:
$ lnk-parse-1.0/lnk-parse-1.0.pl  /home/hajma/.wine/dosdevices/c\:/users/Public/Desktop/Heroes\ of\ Might\ and\ Magic\ 2\ Gold.lnk 

Link File:  /home/hajma/.wine/dosdevices/c:/users/Public/Desktop/Heroes of Might and Magic 2 Gold.lnk
Link Flags:  HAS SHELLIDLIST | POINTS TO FILE/DIR | NO DESCRIPTION | NO RELATIVE PATH STRING | HAS WORKING DIRECTORY | HAS CMD LINE ARGS | HAS CUSTOM ICON |

but when I run
dosbox -conf ./dosboxhomm2.conf -noconsole
the game doe not run in full version, complaining about missing CD in the drive.
Here's the necessary change to the config file:

$ diff -u dosboxhomm2.conf.orig dosboxhomm2.conf
