***********************************************************************
Chartmaster version 6.05
***********************************************************************
From: Lloyd Borrett
President, Melbourne PC User Group,
Melbourne, Australia.
Sysop of the "PC Connection" IBBS on +61 3 528 3750.
CCITT V.21 type modem required. 300 baud only.
I downloaded A.S.P.'s unprotection mechanisms for 'Signmaster' 5.04 and
'Chartmaster' 6.04 on Monday 26th November 1985.
Wouldn't you know it I had versions 5.05 and 6.05 respectively.
I've retrofitted a patch that seems to be okay.
CHARTMASTER 6.05
----------------
1. Rename CM1.EXE CM1
2. DEBUG CM1
3. D CS:A51
You should see 75 03 E9 09 00
E CS:A51 90 90 EB CF 06
W
Q
4. Rename SIGN SIGN.EXE
NOTE:
-----
1. Still requires a diskette in the drive, but not the 'KEY' diskette.
2. I wasn't able to determine what the second part of A.S.P.'s method
did, and they seem to be working fine without it.

Unprotecting ChartMaster version 6.2 - 1/19/87 - by Row Jimmy
(with thanks to the Freebie Fixer)
Version 6.2 uses the same copy protection as 6.1, but in a different place ..
follow these instructions:
copy cm1b.exe to cm1b.xxx
debug cm1b.xxx
-s 000 ffff 75 68
you will see something like
XXXX:CCB7
type
-e ccb7 75.eb <cr>
-w
-q
rename cm1b.xxx to cm1b.exe and you're off and running!
** copy protection is a foolish game **
** don't play the game **
