Hello,

thanks for your work on the engine. I've been using this "variant" in the past few months and I'm very happy with it, it includes already the OpenAL stuff:

Any chance to see this and the dhewm3 branch merged? It seems most of the issues pointed in the iodoom3 bugtracker are fixed either here or there.

I chat with dhewg regarding development, and a merge may happen eventually some time in the future, but not yet. In either case it's fairly easy for me to pull over patches (or vice versa) and OpenAL support shouldn't take too much time.

There are some issues I have with merging code bases which I'm not going to go into in detail here. I feel that many "free-time" hackers, including myself, have their own vision of how development should be done and that doesn't necessarily align with others...
