Unprotect for YS


 BE SURE TO BACKUP YOUR THE PROGRAM DISK BEFORE STARTING AND USE THE
 BACK UP FOR THE UNPROTECT.
 Modify only the backup copy!!!

 First you should rename the file or files
 YSCGA.EXE TO YSCGA
 YSEGA.EXE TO YSEGA
 YSTDY.EXE TO YSTDY


 Ex. C>rename ysega.exe ysega

 Next Load program into debug...

 Ex. C>debug ysega

 Then Follow the sample debug session:

     -s 0000 ffff bf 07 00 b8 06 02
                                  :   Search of protection pattern

     XXXX:YYYY                    :   The search will return one address.
                                      If more than one is returned
                                      this unprotect may not work.

     -e YYYY eb 73 90             :   Edit the contents of the
                                       returned address

 Now write the new game game back to the disk:

     -w  <Enter>

     Writing XXXX bytes

 Then Quit Debug:

     -q  <Enter>

 Now it is time to rename ysega back to ysega.exe

     C>ren ysega ysega.exe

 Now try to run the new (Hopefully) unprotected version of YS

     C>ys
