Function find_initial_gameexe_path 

pub fn find_initial_gameexe_path(project_dir: &Path) -> Result<PathBuf>

Resolve the Gameexe file used by the original startup path.

C_tnm_ini::analize_func() opens module_dir + Select.ini.first_dir() + LCL_GAMEEXE_DAT; Gameexe is therefore selected from the same initial append as Scene.pck, not independently from the project root. Localized candidate names are retained for this port.
