how to compress back into .dat

[dusknem]

I can't figure out how to compress the extracted .s files back into a .dat to put back into the game. I'm not familiar with these kinds of tools, unfortunately. There aren't any instructions on how to do this part so I'm stumped

you need to run something like this, -c means to create the .dat file
igtool.exe -c folder_of_s_files output_dat_file
