Over the years many created maps, mods and videos for this game. I will start by posting my creations and recommendations. I hope many will expand this list.

I'm trying to play the Argas Effect but it crashes really early on when Kirk gets in the turbolift and selects a deck

also tried starbase 11 and it didn't load at all

anyone else tried these mods with this GOG version yet?

I will try it on the weekend, but could you give me some more information about the problem and how you installed the mods?

Did you increase the in the config the /seta com_hunkmegs? The original values are to low, you have to set them to something like 256.
