Hi, can this project be run with Ghidra 9.0.4?

I have this error and it seems to not work.

Thanks !

It looks like those "unknown" registers are a relic of the skel pspec stuff that the author just didn't change at all. those errors should be harmless I think. The real error (at least for me) lies I think in a few lines below (where I think there's some memory overlap)

In other words, pretty sure depending on what you're using it for, the code here is (probably) pretty broken
