Download this:

1) Install Fallout 1 from GOG.com
2) Find and install "Fallout_1_TeamX_Patch_ENG_1.2w" (either via nma or just google)
3) Install "f1child_patch" (again, nma)
4) Install "fallup13" - this is the TeamX patch 1.3.4 (nma)
5) Install "f1npcmod" from TeamX (again, nma)
6) Install "sfall1" (from
http://timeslip.chorrol.com/sfall.html)
7) Install "Fallout1_High_Resolution_Patch_v1.3" (nma)
8) Open f1_res and set AUTO_SCRN_SIZE = 0, then your desired resolution (I use 800*600, anything above is just too darn small for my taste), then if you want, change the way ingame movies work, either fullscreen or not....up to you.Same with movie subtitles.
It should work without any problems - I finished the game with zero bugs or problems with this procedure.
