Hi,
Prehistorik and Prehistorik 2 dont need gog file, and don’t have it. Just copy folder with Prehistoric on you android device. On android create folder “Games” and put Prehistoric there. You must grant read/write permissions on “Games” folder. Then create new game profile set “Main program” to prehistoric.exe (or similar exe inside Prehistoric folder). You don’t need to use expert settings (uncheck it).
