Holy cow, You’re right.Sonora is standalone, you don't need to install F1 or F2.
For sfall, you can check my sfall support pack for Sonora.
I’ve installed everything besides Fallout 1 GOG and now everything works fine.
„Fallout_Sonora_1_15” + „Fallout_Sonora_DLC_1_15” + „fallout2-ce-windows-x64” (1.3) + „sonora_eng_DLC_script” + changes in „fallout2.cfg” („russian” -> „english”).
Now everything works fine when I start the game using “fallout2-ce.exe”.
Thx 4 help mate.
