I found this emulator on a BBS in Bavaria (still, it appears to be virus free
,-). In reply to the following note which was placed in the original ZIP
file, I take the program *absolutely* seriously, it actually emulates a C64
quite closely. Unfortunately, SID and VIC, the sound and video chips are
hardly emulated, so that most "professional" programs (which make use of
sprites and Hires graphics) do not run with reasonable results.
Unfortunately, an inquiry to the author of the program at
mate%mubo.abg.sub.org@ira.uka.de (Martin Freiberg) failed. I would like
to hear about what you learn (e.g. patches?). See the address below.

Here is the note which the author supplied
------------------------------ C U T C A T ------------------------------
The program C64.EXE is an emulator for the well known home computer from
Commodore. This program is not to be taken too seriously but it brings back
pleasant memories for me. Several notes about the program.
- Runs only on PCs/ATs with a Hercules card
- The keyboard is the original 64, so [Shift-RightArrow] to go left (numeric
keypad only if you have a 101 key keyboard), [Shift-DownArrow] to go up, [\]
for the equals sign.
- One can end the session with 'SYS 1' [Enter]. The same thing happens with
an undefined opcode.
- [Ctrl-Alt-Del] causes a reset. [Num] stands for [Run/Stop] and [Scroll] for
[Restore]. A Restore can also be issued by [Num-Scroll].
- It emulates one VC1541 floppy, which contains a machine language monitor on
a chip. It can be loaded with 'LOAD "MONITOR" ,8,1' and called with 'SYS
49152'. Only one program can be stored. The two format commands can not be
used.
- Bank switching 1 is emulated (try 'POKE 1, 0').
- Timer 1 is partially emulated by the CIA at address DC00 <IRQ>.
- The VIC functions of different character attributes <not Multicolor> and
background color <POKE 53281, X> are emulated. Also, the key combination
[Shift-Alt] works as [Shift-CBM].
That's enough. My proposal: put it in the AUTOEXEC.BAT of someone you don't
like...
[Translator's Note:
I tested this using the Hercules emulation mode of my VGA card (a Paradise).
There were extra characters on the right of the screen and the bottom line was
incompletely displayed. Presumably this was due to a fault in my VGA card
rather than this program; maybe yours will work better.
You probably know much more about the C64 than I do; so don't write to me to
ask for help in using this emulator. (In particular, I have no idea about
how to take a Commodore disk and turn it into one of the *.41 files the
emulator uses!) But, if you have corrections to the translation or additions
to the documentation, please send them to me and I'll incorporate them.
