Found a few weeks ago a developer working on a Player Character Editor for Pool of Radiance and for Curse of the Azure Bonds. Not sure that he’s released it, I assume he will at some point.
Bill’s Gold Box Explorer is awaiting a release any day now, but the latest code renders all graphics from the SSI Games. I did release a beta build on FRUA Hacking UA list.
I also got an email from Patrik saying he’s working on a port of Pool of Radiance in C++/GTK, so will link once that goes public.
