Ouh. Even on roguebasin your official site changed to itch.io, I assumed that the old one was deleted already. Thank you very much, it's exactly what I was looking for! But shame on me, the old site is the 5th result in google...
Lack of support for Mac doesn't bother me - as I wrote, it's for archiving purposes. I'm just trying to save as much roguelikes as possible, including every released version.
I remember playing 1.6.4, I'm going to try 1.7.0 as well, definitely :)
