As for Zelda classic itself.
You have basically two groups interested in it.
Players and builders.
Players get irritated because they have to use the version that the quest was built in, and often don't resulting it having to start over or just give up on a quest that they have hours and hours invested in trying to play.
It's the same with builders.
I have two quests that I have over 2 years work in combined setting on my hard drive unfinished.
Both have become corrupted by newer builds at least 4 times, and weeks and weeks have been spent repairing them.
They can't be finished under the present conditions.
The people here now haven't waited the 4 years many of us have for a stable release, and they'll one day give up hope as well if things don't change around here, it's just common sense.
What is to hold people here with conditions such as this?
Build it, and they will come, otherwise, what's the point.
