Sad news, indeed.
I have also question (and request) about tools. Do you have any editor that would work with English Dominators/Reboot version and allow unpack text quests, then repack them back into appropriate file? there is a guy called Starcleaver who is cleaning up (and made a darn good job I must say) SR2 English translation, but he cannot do anything about text adventures, because lack of tools. Could you somehow help him out?
Here is his topic on totalgaming.net, where he mentions the issues he has (also in last post). He had also a
topic on Steam boards also, if it helps.
