your screen Greetz only to the BEST OF

Comments : The Dotty virus copies always to the same memory
address => $7F000. It uses the DoIO()-Vector to infect
other disks. Furthermore the virus uses the KICK-
Vectors to stay resident in memory.
If the virus infects a disk, a new patch will be
installed in the Vec5-Vector => $94(A6). This patch
checks if a special value reaches 21000. If this value
is now reaching 21000 (^see above) the virus executes
a GFX-Routine. But this routine is sooo LAME coded (HA
HAHA) that you will only getan ENDLESS-LOOP.
