droceRoG is a SGF file viewer for PocketBook ebook readers (6" and 9" series). SGF file contain Go games, probably with variations, comments, and marked positions. The sources of an alpha version have been created by me in the beginning of the year and are now uploaded to GitHub. Check out droceRoG on GitHub for further info.
When a stable version is reached, also a compiled executable is placed on GitHub. At the moment, small bugfixes are still to be done.
