Homebrew I am working on which is crashing (it will be missing files so it won't crash the same way mine does, but it has the same missing stacktrace behavior) ReflectionMetaDumperWiiU.zip

Proper PPC stack traces can only be generated if Cemu is running in interpreter mode (by setting game profile CPU mode to interpreter or launch Cemu with --force-interpreter). In recompiler mode stack traces can not always be generated due to the way stack is managed. #641 will fix this partially

The stack trace i'm looking at is one for Cemu, not the application running. Is there a way to get one for the application or is that out of scope for Cemu?

What I said applies. It should print two stack traces, one for Cemu and another one for the PPC application running within it (if it is the PPC code that causes the crash)
