User guide

Main menu

“Edit…”: review a previously recorded game along with commentaries
“Create…”: record a new game with commentaries
“Options…”: change default
“Edit an SGF file…”: select SGF file and validate.
“Quit”: go back to the main menu.
“Create an SGF file…”: select and change the names for the game and the players by selecting them with the stylus (an input keyboard will appear).

Select the handicap value. For this first release, the komi is set to 7.5 (french official value) but in the next release, it will appear as a parameter.

Validate to create the game and view the goban. We assume that the placement of the handicap stones are the regular ones (no manual placement at this time).

The handicap stones are automatically placed. It's white's turn to play.

If go backward and then change the selection, all nodes after this one will be automatically deleted (no variations are handled at this time).

Use the commentary icon menu to add a commentary to the current move (using the input keyboard).

Save SGF file by selection the save icon menu and typing in a filename (don't add the ".sgf" extension, it will be done automatically).


For now, DSgf doesn’t handle variations, even in read-only mode, so such SGF files are useless for now.

Furthermore, if you are trying to load big SGF files (>100Ko), the loading time will be quite long and you could even get some “memory full” error if there isn’t enough RAM to handle the SGF (the NDS has only 4MB of RAM, and DSgf already uses 1.5MB!).

DSgf analyzes the SGF files at loading time, to ensure afterwards a smooth navigation/display of the game. The drawback is that the data structure uses a lot of memory.
