How can I make blue shift and opossing force work in nghl?

Hello.

I’ve searched around and I can’t really find how to make it work, I tried quadrazid’s gfc (Half-Life basics, tutorials, downloads - Helpdesk, ask questions here.) but it doesn’t work in both games, blue shift it shows the main menu for a second without any buttons and it crashes and opossing force just crashes without ever popping up.

so… any solution?

thanks.

For opposing force just download the GoldSrc package and copy gearbox_WON to your nghl folder, as for blue shift, I don’t think that it works on nghl.
