I tested 2 versions of this game also in mame.
Here are the sha1sums of the tested disks :
Both disk versions didn't work, testing them both on MAME, using the c1541 or the c1570 drive.
Also tested them with different reversions, without success.
Seems that both drivers indeed have issues.
Also I can confirm that they both work on VICE and lr-vice.
I found that VICE includes a CLI program called 'c1541'.
With this program you can "attach" the disc image and later "extract" the files.
The disc contains a file called "Chwat+", a 'prg' file.
After extracting you can exit 'c1541' with "exit".
Then rename the file to Chwat+.prg.
I did it like this :
c1541 (VICE 3.7.1 SVN r44618)
Copyright 1995-2022 The VICE Development Team.
C1541 is free software, covered by the GNU General Public License, and you are
welcome to change it and/or distribute copies of it under certain conditions.
c1541 #8> attach Chwat_1996_Timsoft_cr_F4CG_t_2_F4CG.d64
c1541 #8> dir
0 "ass presents: "
187 "chwat+" prg
477 blocks free.
c1541 #8> extract
c1541 #8> exit
xx@xxxxx:~$mv Chwat+ Chwat+.prg
A prg file can be loaded directly with the '-quik' option.
Now the game works over here.
Don't forget the type "run" ;-)
Once loaded into the c64, you might want to try and save the prg file to a newly created disc image.
Perhaps that will work if you really want it to load from disc.
Although I would recommend loading prg files because it is much quicker.
