I don't think you need to write the .sgf file while doing the rollout. 

I think it can be accomplished by having a local matchstate and plGame in
BasicCubefulRollout, and then call AddMoveRecord[*] for each move and
cube decision (check play.c where there is lot's of examples
around). At the end, you just call SaveGame from sgf.c.
You have to set board, cube position etc first. See CommandSavePosition
for an example.

This approach should be very generic.

We can add new moverecords for truncation (either bearoff or just normal
truncation), and a new moverecord for the rollout result (win, lose +
variance reduction for this game).

[*] You have to write a wrapper for AddMoveRecord as it operates on the
global matchstate ms.
