My MD5 Checksum is:

Ram Disk:> Ram Disk:> md5 work:dukenukem/DUKE3d.grp
cf aa 62 fb 05 13 78 ac 5b a6 18 8d cf 07 c2 76
Ram Disk:>

So as lon as i use a correct MD5 generator there must be a difference
between my and the other file.

So please could someone be so friendly and post a little tiny petite
link to an archive with a working demo file ?

Thanks for everyone who will do this difficult work for me.
