You should ask the author of the emulator. Anyone can write code that 
doesn't work.

Anyone can also say something doesn't work without giving details about what 
doesn't work. I assume that the emulator that you are speaking of is in fact 
capable of running SHR programs in ProDOS 8. If not then that is your 
explanation.

The only conclusion I can come to since these SHR programs work a a real 
IIgs, and on an Apple IIe with a VOC, and on an Apple IIe with a Carte 
Blanche and Charlie's SHR Mods, and on Kent Dickey's kegs32 emulator in 
Windows, is that either the emulator you mention does not work, or the 
system that the emulator runs on does not work, or both.

Since doing these demos of mine in both Aztec C65 and cc65, several 
emulators etc. have been found with graphics mode bugs, which indicates that 
they are either poorly written, poorly tested, or both. Perhaps nobody else 
is using them so did not notice. There may be a reason why nobody else uses 
emulators that do not work.

There are other 8-bit programs out there that use SHR written by other 
authors... SHRView for example A logical place for the author of an emulator 
when trying to detect a bug in his software while running 8-bit programs 
that use SHR is to test with several programs.

In any case, if you review the code for my demos, it is very straight 
forward and well documented, and transparent You should be able to find the 
emulator bug and fix it yourself, or just use an emulator that works.
