Ghidra Version is 9.2.2

achan1989 commented 3 years ago

It worked last time I tried it (though that was a while ago). Is there a file at /opt/ghidra/Ghidra/Processors/65816/data/languages/65816.slaspec and does it have sensible file permissions? Same for the parent directories?

Please note, that there is no 65816.sla file... is that normal?

oziphantom commented 3 years ago

mine has a 65816.sla file and it is 1,4967KB.

hellow554 commented 3 years ago

Any idea how it gets created? https://github.com/achan1989/ghidra-65816/tree/master/data/languages doesn't contain such file.

achan1989 commented 3 years ago

If I remember correctly, the .sla file is auto-generated by Ghidra after it loads and processes the .slaspec file.

@hellow554 your data files are all owned by root, so unless you're running Ghidra as root (which is probably a bad idea!) Ghidra won't have permission to read the files.

hellow554 commented 3 years ago

Ghidra is installed to /opt by my package manager pacman. So I copied your files into /opt/... as well and gave them the same file permissions as all the other processor types as well. That should be the right way to do. Is there a specific reason the .sla file is generated on the fly? Why do other processor specs to not do that? :/

achan1989 commented 3 years ago

I don't remember, it's been a long time since I've used this module.

qwertymodo commented 3 years ago

The issue seems to be a handful of unused labels in 658xx.sinc getting treated as errors. Commenting out the labels with a '#' at the beginning of the following lines seems to solve it

658xx.sinc:1579: <binary>
658xx.sinc:1622: <binary>
658xx.sinc:2018: <to_emulation>
658xx.sinc:2044: <to_emulation>

This should have been fixed by PR #13 which is now merged.
