Hey! Thanks to propbeanie's new patch, the Bismarck works! Here's a video of me "testing" it. Sonar guy first said it was a merchant. After I ID'd it with the periscope he switched to warship. That was nice of him.
This video was performed by an expert in SH4. Don't try that at home, especially the chronometer in front of the torpedo fire button trick.
The battle plan is to mix up v0.30 public beta tomorrow and post for all on the Subsim Download area.
