@Daniel "Dan" Acerbi Rocha RE1. It was always possible to pass time in the cave to after midnight to be able to enter v13 in Fo1. RE2. I don't know what do you mean by "this version of sfall" but v1.8 of Sfall1 made by Crafty is/was latest up until present day, I have no idea if there was a release of something newer. RE3. I personally always set mouse speed in sfall1 to 150 (wich is 1.5x default [a.k.a. 100 default]) plus mouse slider in the ingame settings to the max. RE4. I'm able to set the number of sound buffers in sfall1 v1.8 up to 127 wich is the maximum, and the game starts fine. I am not sure however, if the game registers additional sound buffers ( my integrated soundcard has 32 built-in sound buffers).
