Is there any way of playing the captain's game? It came with the scenario builder expansion. I can find the corresponding .bat (gnbsp), but even when trying to start this directly in DOSbox, it simply crashes. From gog-galaxy, there seems to be no way of starting this part of the game at all. Please help, since this was the reason for me to get this version here on gog.

OK, sorry guys, I solved it. There are two folders for GNBNA (GNB1). If you copy the one called "GNB1flop" into the folder of a working DOSBox on your machine an start the GNBSP.BAT (from DOSBox, then it works.
