ÄÍ[ Introduction ]ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÄÄÄ

  My english is not too good, but I hope you understand it.
  UnPackStop is a little tool, which protects your executables against
  generic unpackers and makes hacker's job harder ( I hope :)
  It's not an unhackable protection, but if you can't hack it, it may be
  better than your protection.


ÄÍ[ Usage ]ÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÄÄÄ

  It's easy to use UPSTOP :

  UPSTOP <source> [target] [/d] [/p]

  /d : disable the file size check
  /p : to prevent dumping ( maybe incompatible with shell type progs )
       ( use this switch on PASCAL & C & .. compiled progs )

  Examples : - UPSTOP ABC.EXE
               it creates ABC.UPS backup file and ABC.EXE protected
               file
             - UPSTOP ABC.EXE ABCP.EXE
               it creates ABCP.EXE protected file

  If the source file has overlays or it's a new-EXE you will get an error
  message.

    - if you have any idea to make it better
    - if you want more information about UPSTOP
    - if you release a protected program
        ( you should send me a registered version )
    - if you think UPSTOP is the best :)

  I don't want to say : UPSTOP better than *STOP and ...
  I hope you think this :)

  I don't ( want to ) steal any code, I use only my tricks. ( Yes, I'm using
  INT1, INT3, DRx, stack,... tricks, but the method of using is my idea ).
  So if you find a trick which is similar with your trick, it's a chance !
