The file \msrebirth\msr\gfx\shell\strings.lst doesn't appear to be used. It is a copy+paste of the strings.lst from the Firearms mod, and should be removed.
Strings for the menu appear to be loaded from \msrebirth\msr\resource\gamemenu.res instead, and custom code seems to have replaced the need for anything from strings.lst.

Please double-check me though!
