Comments : The Mutilator Virus only works on a few systems.
As you can see above the virus needs Kickstart 1.3
and a special (FAST)Ram called `Ranger Ram`.
People who are booting with an infected disk and
who can`t afford the above mentioned conditions will
see a GURU ! But if you have such a Ram + Kickstart
the virus will do the following:
1) The virus copies itself at $7FAD0 and changes the
coolcapture-vector to stay resident.
After the next reset the virus patches the DoIO() &
The DoIO()-Patch is used to infect other disks.
Every time when the Supervisor()-Vector is used by
the system, the virus increases a value by 1. If
this value reaches 224 (and an other 160) the virus
executes a GFX-Routine with an endless-loop. But
this routine has an programming-error (Color-Initial
Routine is the last S..t!), so you will get an black
After 3 infects the virus gives out an alert:
"THIS IS THE NEW MUTILATOR VIRUS !"
"BY MAX OF STARLIGHT!"
