What happens if you just extract it to some random (i. e. unused otherwise) folder and launch the .exe?
You missed the part about being on a
Mac running Catalina (no Wine) So .exe won't run.
I'm pretty sure the SDK doesn't read from the pre compiled rpas, I could be wrong though. So I'm surprised it worked at all.
It has worked on nearly every other game with compiled rpas I have done this on. The
only exception was Time for Dragons where I had to copy the yaml folder and put it into the SDK. Heck, this will even work on Renpy written directly for the mac (ie a full application) so I don't have to wait for the OS's verification process.
I evne took the files and put them in the older mac version (which does work) and got the same error.
Running ahitr.sh directly produced
