Okay.

First use the list_contents batch file to produce that listing. Then read off the files you want (it shoudl be pretty obvious, but since I don't have M2TW installed right now I can't give them to you) and use the --filter command to extract specific files.

The best way to do this would be by copying the unpack_all.bat file, opening it in notepad and adding that command at the end. Remember that * is a wildcard; identify the common naming system of the files you want and wildcard the rest to get them all.

I'll give you more detailed help in a few hours, if you need it, once M2TW has been installed.

You'll probably want something like --filter loading_screen_symbol*.*
