Unprotect for Front Page Sports 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
FB_MENU.EXE (as always it is inadvisable to modify your original). Search for
and make the following changes:

Original: 75 05 B8 01 00 EB 02 33 C0 88 45 0E
| |
Changes: 90 90 B8 01 00 EB 02 33 C0 88 45 0E

Write the file out and you are done! Answer anything when it asks the
question.

For reference this is a dump of the 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/
