Sorry that this is why I have to come back to the blog for a bit, but I don't have any choice in the matter.
Effective December 1, 2012, I will no longer be supporting RomTerraria in any way, shape or form, and I will have to take down the auto-update version.
The source code will still be available and is released under the BSD license.
There are a lot of things going on behind the scenes, not all of which I'm going to be able to talk about until around this time next year, but there is some exciting stuff coming which requires me to do something I don't want to do first.
