Due to the recent patch for Halo, I will update Gandanur to work with 1.10 in the next few weeks. I can't give an ETA, but there will be an update.
It was a bit of a surprise to see people still using Gandanur, but that's a good thing! Halo is still a special community, as evidenced by this patch to an 11 year old game. And the fact that community members such as Technut, kornman00, and btcc22 helped made the new Halo 1.10 patch possible is an amazing thing to see.
Update: patch will be released before, or on, 30 june 2014.
