More about Sharp's X68000 Viri in Japan
Artdink Inc. is now distributing the vaccine against the virus
which was contained in the simulation game software "FAR SIDE MOON".
It says that the virus in question is attached to the battery
backed-up area of the SRAM of X68000 and if the system is booted by a
floppy without the protect seal, the floppy is contaminated. It is
named "NX68K IPL V1.02". The effect of the virus is it will destroy
the data on the floppy after July this year. This virus started to
prevail among X68000 users last December.
Artdink started to sell "FAR SIDE MOON" for X68000 on April 13
(Friday !!!!). 3200 sets have been sold before calling back due to
the virus. Not all the articles are contaminated, only those in
limited lots. This software consists of three floppies, among which
only game disk is contaminated while system and data disks are not.
If a user boots the dirty floppy according to the manual, the virus is
not transfered to the SRAM.
The vaccine, named "DOCTOR" was written by the editorial office of
the journal "Oh! X" for X68000 users. It initializes the SRAM and
make it immune and it kills the virus on the floppy. However, it is
effective only to two viri V1.02 and V1.05.
