Just a couple of small tweaks I use on my setup
"Stealthy" mouse cursor.
New crew management screen background (Type VII schematic).
Periscope up/down sound(originally taken from Gunther Hessler's SH4 ultimate soundmod but modified to mono and slightly lower gain for SH3).
JSGME ready,just remove anything you don't want
