First time out of the vault

Hello. I can not get any of the EtTu mod to work.
I have never played Fallout; I just purchased F and F2 from GOG. I downloaded the F Et Tu mod from GitHub. I followed all instructions in the ReadMe. I extracted EtTu into the F2 directory, I ran the Undat.exe and chose Master.dat from the F1 directory and the Fallout1in2 folder as the extraction target. I selected some of the options in the fo1_settings.ini file. Then I started F1 and began play, but none of the modifications are present.
Please help me to determine what I have done wrong. TY.
