Tradewars 2002

[Ryan Underwood]

hi,

Can someone with a bit more knowledge of dosemu internals try to figure out
the problem with this program?

DPMI version:
ftp://doorgames.org/bbsfiles/space_doors/2002d309.zip
non-DPMI version:
ftp://doorgames.org/bbsfiles/space_doors/2002v309.zip

I tried both versions, under dosemu 1.0.2 with latest freedos, and after
starting a bigbang (to initialize the game), they exit with a:

File Error (1) - TWCfig.DAT : Invalid Function

Actually, it works fine under DR-DOS, so is this a FreeDOS problem and not
a dosemu problem?  If so, how would I go about getting relevant debug 
information to send to the FreeDOS developers?

Thanks!

I'm not sure which FreeDOS version you are using. The program you
mentioned seems to run just fine for me (with FreeDOS kernel 2028).

DOS Partitions are read only

I have DOSemu up and running.  I put the ms-dos components (from win98) in the 
"boot drive.  I boots fine, but when I lredir the other dos partitions, I 
cannot write to them.  I have installed and am running as a user, not root.

An interesting related insight: Trade Wars will refuse to run multi-player
with anything BUT FreeDos (on a redirected file system).  It has to do
with the file locking issues in mfs.c, or at least it seems so.

There is a patch floating around that deals with this problem for just
about every other game of this nature, but TW is doing something slightly
different and I haven't quite figured out the details.

check your /etc/fstab; see "man mount". If you're on a true multiuser
system it's best to create a dosemu group. But if you're the only one on
that computer who uses Linux then you can just as well make the DOS
partition owned by you, ie. something like

         /dev/hda1 /dosc msdos defaults,uid=500,umask=022 0 0

in your /etc/fstab. Replace 500 with your real UID.
Use vfat instead of msdos if you want to see long file names in Linux.

Below is the relevant excerpt from README.txt.

    4. The msdos partitions, that you want to be accessable through
       Section 5 should be mounted with proper permissions. I recommend
       doing this via 'group's, not via user ownership. Given you have a
       group 'dosemu' for this and want to give the user 'lermen' access,
       then the following should be
          + in /etc/passwd:

         lermen:x:500:100:Hans Lermen:/home/lermen:/bin/bash
                      ^^^-- note: this is NOT the group id of 'dosemu'

          + in /etc/group:

         users:x:100:
         dosemu:x:200:dosemu,lermen
                  ^^^

          + in /etc/fstab:

         /dev/hda1 /dosc msdos defaults,gid=200,umask=002 0 0
                                            ^^^

       Note: the changes to /etc/passwd and /etc/group only take place
       the next time you login, so don't forget to re-login.
       The fstab entry will mount /dosc such that is has the proper
       permissions

       ( drwxrwxr-x  22 root     dosemu      16384 Jan  1  1970 /dosc )

       You can do the same with an explicit mount command:

          mount -t msdos -o gid=200,umask=002 /dev/hda1 /dosc

       Of course normal lredir'ed unix directories should have the same
       permissions.

Interesting.  Well, I was able to get it to work using the latest dosemu-freedos-07f
"Ripcord" distribution, and copying in the latest kernel.sys and command.com
from the freedos sourceforge project.  So it appears that this was a problem
in the old dosemu-freedos.tgz, which is now no longer an issue.

I will post here if I discover anything more.
