Yes it's finally out after many months of hard work.
Head to the Gensokyo.com article
here to grab it.
You need to be patched up to 1.06 to use it. Like the IaMP patch, it will not affect your install at all so when hisoutensoku comes out it should work with the original just fine. If you had installed the english weather patch, you do not need to remove it, this will run over it without any problems.
It will play fine with non-translated clients, though kanji deck names and the like won't show up on your side.
Report any bugs or issues here or at gensokyo's article.
Thanks go out to mauve, Halbarad, Rotals Nartnona, _dk, Akira, TMN, and Mefidex for all their hard work on the patch!
As for those wondering why it took so long, note that SWR has 3 times the text of IaMP, over 300 edited images, and more hacks then any 3 other english touhou translations put together.
