Yeah i have sources i wrote it
But their quality is not so good ... but its quite simple app anyway.
I think bigger problem is actually if there is need to have such editor with such graphics ? lets say there are 2 people who can develop it and lets say 10 people who use it.
Another thing is compatibility with current OXC.
Another thing is define color palette and things like size of tile etc.
So i just gave the basic idea of tool to remake graphics without copyrights problems.
