Just a tip to those who are finding the default.ini not found error: try putting the bin files in the same folder as the application, then dragging them onto the application. It worked for me, after searching for so long to fix it...
Also, a question I have is, that this editor shows monster point editing capabilities, has anybody tried it? I don't know if that's feasible/within legal bounds since that does in fact change a value that is somewhat related to currency
Edit: New update seems to have made this app invalid for now
