Unprotect for Perfect General

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
GENERAL.EXE (as always it is inadvisable to modify your original). Search for
the following bytes and make the following changes:

Original: 75 0E 9A 0A
| |
Changes: EB 09 9A 0A


Write the file out and you are done!


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