SmartGo One can now read go games in file formats other than SGF: UGF, NGF, and GIB (with file extensions .ugi, .ngf, and .gib). UGF is popular in Japan, NGF is used by the Korean wBaduk server, and GIB is used by the Korean Tygem server.
SmartGo One will show thumbnails for these files, with the file extension indicated in the lower right corner.
Support for these file formats is read-only. If you make changes to the game, it will be saved as SGF, overwriting the imported file. Paste SGF will also accept games in those formats.
Unfortunately, I don’t have the spec for any of these file formats, so the files are interpreted based on reverse engineering as well as comments at Sensei’s Library. I’d love to get more sample files so I can make sure my code handles all the corner cases. And if you run into files that are not handled as well as they could be, please send me a copy at email@example.com. Thanks!
Also, please let me know if I should revive my old code for reading the Ishi (.go) file format. Is anybody still using that one?
