Good!
Please Osmium, also add sounds to the snorkel up/down. itīs completely absent on Sh3 and an old request from comunity. A lot of ppl (me included) have tried to found a solution but never acheived. With this new Anvartīs tips is now easy to see that will be possible to do using the snorkel commands. I made a mod some years ago (IIRC "Snorkel for all") that adds fx&RWR to all snorkel and installations. it uses Anvarts state machine controls and then the sounds can be finally added!
