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:

1. Use a hex editor to open DUKE3D.EXE and change the 'O' at location 0x110 to somethine like 'L'.
2. 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.

1. Backup your original DUKE3D.EXE file in case you make a mistake:
   • COPY DUKE3D.EXE DUKE3D.BAK
2. Rename the DUKE3D.EXE FILE to DUKE3D.BIN
   • REN DUKE3D.EXE DUKE3D.BIN
3. Run the DOS debug program on the DUKE3D.BIN file:
   • DEBUG DUKE3D.BIN
4. At the "-" prompt type:
   • E 200 58 <return> E 210 58 <return> W <return> Q <return>
5. Rename the DUKE3D.BIN file to DUKE3D.EXE
   • REN DUKE3D.BIN DUKE3D.EXE
6. Edit the DUKE3D.CFG file
   • EDIT DUKE3D.CFG
7. Look for the line containing: Environment = " " change it to: Environment = ""
8. Look for the line containing: Out = 1 change it to: Out = 0
9. Save the file and exit back to DOS
