How can I change .ngf files to .sgf? I get the ngf's when I look at my wbaduk gibo.

Moyo Go Studio let's you open the files and save them as .SGF.

You can check other programs like Drago and MultiGo, maybe they are capable of that, too.

Multigo does for sure.... Not sure about drago...

I did write a Perl NGF to SGF conversion program if anyone wants a copy please ask.

It needs to learn how to put down handicap stones, especially 3.
