Something I do wish which could be fun to pair up with this tool is a decompiler/disassembler for i6. I did find GitHub - wertercatt/mrifk: A decompiler and disassembler for the Glulx virtual machine. but it seems to have been forgotten.
The tool was also discussed here but that topic seems to have also dried up Reverse Engineering the Source Code from .gblorb - #23 by aschultz
