try with this ARB adaptation for wac5.2 :
https://www.subsim.com/radioroom/sho...d.php?t=239167
It works : "-Salvo selector numbers visible at periscop view F3, at tdc view F6 and at uzo view."
go in the mod there is TDC8.tga (in data\Menu\Gui\TDC)
and go in menu_1024_768.ini, you will find it too.
