Removing Duke3D dongle for Australian
Versions
The following information was posted to usenet in 1996. It is
here as a reference, although I suspect that there's a properly maintained FAQ
or HOWTO somewhere... Please note that these are not my hacks, and I can't
guarantee anything...

Method 1 : Requires a HEX Editor
For those who missed it, to re-enable adult mode on the
Australia/New Zealand version:
- Use a hex editor to open DUKE3D.EXE and change the 'O' at
location 0x110 to somethine like 'L'.
- Now use a text editor to change the "Out = 1" line in
duke3d.cfg to "Out = 0".
Got it? good. :-)
Method 2 : Use DOS DEBUG utility
I found this info at a website. Be sure to make backups of any
files you are about to change.
- Backup your original DUKE3D.EXE file in case you make a
mistake:
- COPY DUKE3D.EXE DUKE3D.BAK
- Rename the DUKE3D.EXE FILE to DUKE3D.BIN
- REN DUKE3D.EXE DUKE3D.BIN
- Run the DOS debug program on the DUKE3D.BIN file:
- At the "-" prompt type:
- E 200 58 <return> E 210 58 <return> W
<return> Q <return>
- Rename the DUKE3D.BIN file to DUKE3D.EXE
- REN DUKE3D.BIN DUKE3D.EXE
- Edit the DUKE3D.CFG file
- Look for the line containing: Environment = " " change it
to: Environment = ""
- Look for the line containing: Out = 1 change it to: Out =
0
- Save the file and exit back to DOS
