I was absent for most of this week due to a visit of my parents in law.
I will resume work on this project / the toolkit the coming weekend (2nd May).
As a little status update: the TR2 packing tool is 95% done, the only special case I still need to handle are TR2 files with header embedded payloads.
Once that is done I will push a new TR2 dump to github, along with the blz2 and tr2 tool source / binaries.
The res unpacker / packer tool source will follow once I finished the packing implementation, that one might be a while, but given all the text that still needs translating on the transifex project I think that's okay.
