I have an idea, and I still have it: to save up money and give the game to my acquaintances from a company that does reverse engineering of software on demand. They will restore the source code for me (there is a guarantee), and I will be able to rework it, at least a little. But the price is really high (but it's worth it).
Maybe you haven't heard, but there is a project called vcmi. They are trying to rewrite the engine from scratch with open-source code. The client is already working, but not everything has been implemented yet.
The source code is here: https://github.com/vcmi/vcmi
The forum is here: http://forum.vcmi.eu/portal.php
(compilation: http://wiki.vcmi.eu/index.php?title=How_to_build_VCMI_(Windows))
If you are a programmer, join in.
For example, I am waiting (and hoping) that someday they will write a good AI. But at the moment, there is no one to do it. So, I'm just keeping an eye on the project
