CyberSnooper is an utility to show instructions that have to be
emulated. It's helpful for Developers to see where they can optimize
their applications.
For experienced users it's useful to see what CyberPatcher has to
handle and where it can be improved if it doesn't handle a certain
instruction.
I have only tested a variety of programs to find the most used
instructions so a lot programs may not be patched.
It's important in what order you start the programs:
1) CyberPatcher and then CyberSnooper.
Now CyberSnooper will output every¹ FPU/INTEGER instruction
that causes an exception.
These information may be helpful when CyberPatcher crashes
for some unknown reason and you want to see what is the last
instruction it saw before it crashes. Please be aware that
Sushi buffers so you usually don't see the last instruction that
may cause the crash. You need a real NULL-Modem link in this
case.
2) CyberSnooper and then CyberPatcher.
Now CyberSnooper is only called for instructions CyberPatcher
doesn't know.
These informations may be helpful if you want to tell the
author(me:-) what kind of instruction CyberPatcher doesn't
handle yet.
CyberSnooper supports Segtracker that can be found in the
Enforcer V37 release and you also need a debugging terminal
or debug output snooping utility like Sushi to see the output.
¹ Every instruction that has to be emulated and causes a certain
exception.
If you have some technical feedback you want to tell me feel
free to contact me.
