Unprotect for Mike Ditka Ultimate Football

Tired of looking up protection codes for that expensive program you bought?
Well we can do something about that nasty protection scheme.

Use the Norton editor (or a similar hex editor) on the hard disk copy of
DAT101.DAT (as always it is inadvisable to modify your original). Search for
the following bytes:

Original: 28 7C 34 C4 (this should be found around 04)
|
Changes: 3E 7C 34 C4

Original: 0B C0 75 BB 83 7E (this should be found around 0BC55)
| | |
Changes: 31 C0 90 90 83 7E

Write the file out and you are done! Simply enter any number when it asks you
the question.


For reference this is the dump of the code part of the program we are
changing.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
