unprotect for GOLDRUSH!

copy protection scheme is bsed on documentation

to remove the copy protection run bat file grush

- the bat file will copy your grdir file
to olddir - this is for your protection
as your version may differ from mine

- the bat file invokes debug to modify grdir

- run sierra to start game

note - if you wish to manually apply the patch

- the offsets in grush.dbg are 100 hex bytes greater
than the file offsets

do to the fact that debug loads everything as a com file

file old new
offset value value

brought to you by SIR GRAHAM working to make your
hard disk more useful - and 80 page books unnecessary

why i did not attempt to break other documentation protected
Sierra games

-- because people have a right to protect their property

why i broke GOLDRUSH

-- i do not like to fumble through 80 page books

remember - this unprotect is for legitimate purposes
only - hard disk execution - and not for the production
of illegal copies
