I downloaded this sub from a Russian site, I think and adapted it to be SH4 v1.5 playable in campaign mode, so far it works fine except for one thing. The surface radar PPI won't work, I get Air warnings and I know there is no scope to operate the air radar but the PPI to detect surface vessels doesn't work, the funny thing is that it works just fine in war patrols but refuses to work in campaign mode, any ideas will be greatly appreciated.
