Подробное описание всех опций (на английском)
Effects of the switches.
The following is only a brief summary. Full details of each H.sie fix can be found in the documentation for the SH3 patch that you have applied.

Realistic Repair Times (V15A or later)
Repair times of all U-boat equipment (periscopes, engines, pumps, sonar) take 60 times longer than before.

Inaccurate range-estimations (V15B or later)
Inaccurate range estimations for Watch Officer and Weapons Officer. No more "god's-eye" firing-solutions. The range estimations are now displayed in steps, which become larger for larger ranges.

Snorkel-Fix (V15D or later)
Speed restriction when snorkelling, dependent on wind speed.

Periscope-Fix (V15D or later)
Restricted periscope usage at higher speeds. Blur effect above 4.5 kts, auto-retraction above 7 kts.

Hydrophone-Fix (V15D or later)
Hydrophones are useless when diesel engines are working (surfaced or snorkelling).

“Crash dive blues” - Bug fix (V15E or later)
Prevents losing control over the sub if you interrupt a crash dive before reaching the designated depth.

Fog warning (V15E or later)
Reduces Time Compression to x16 whenever fog occurs to warn the player. The watch officer also reports "fog sighted" and "fog disappeared".

External torpedo reload fix (V15E or later)
Reload of external torpedoes is impossible during bad weather. Speed is restricted to "slow", and diving is not possible during the reload process.

Internal torpedo reload fix (V15E or later)
Reload of internal torpedoes is impossible on the surface during a storm. You have to dive below 30m.

Watch Officer automatically moves to bridge when surfacing (V15E or later)
The watch officer now automatically moves to the bridge when the U-boat surfaces.

Oxygen-Supply (V15F or later)
Oxygen is divided into two parts: a renewable part (air in the U-boat, ~5-7 hours) and a non-renewable part (bottled O2 supply, ~30-100 hours). Bottled O2 is not replenished when surfacing.

WarNews (V15G or later)
Prevents the irritating drop in Time Compression to x1 every time a piece of war news is transmitted.

BDU-Messages Mod (V15G or later)
Provides 28 different and contextual messages from BdU in response to your status reports.

U-tanker Fix
Allows you to properly dock at a U-tanker instead of starting a new career.

Radar Fix (V15G or later)
Radar automatically switches back to ON state if it was switched OFF in high waves.

Wolf-pack Mod (V16A or later)
Gives you the option to call in a wolf-pack to assist in your attack on a convoy.

Silent-Running Fix (Stiebler)
Causes the U-boat to sink very slowly when silent-running at low speed (<2 kts).

Makes ASDIC less effective in shallow waters.

Warning Dialog Box (Stiebler)
Prevents the drop in Time Compression to x1 when the “WARSHIP SPOTTED” dialog box appears.

Minimum TC (Stiebler)
Sets a minimum value for time compression (default x128) that cannot be reduced by game events.

Change Patrol Grid (Stiebler)
Allows a single request for a new patrol grid after you have explored the original one.

Null Grid Fix (Stiebler)
Creates a new patrol grid when you would have previously received a NULL grid.

Weather Meter (Stiebler)
Changes the Stealth Meter to a weather meter, showing current visibility.

Ship Speed Fix (Stiebler)
Reduces the speed of all ships (including escorts) during storms, making surface escapes more realistic.

Air Torpedo (FIDO) mod (Stiebler)
Simulates the dropping of an Allied acoustic torpedo (FIDO) from aircraft starting from July 1943. Can be evaded by reducing speed.

Radar-Turm fix (Stiebler)
Ensures that fixed and rotating radars are installed in the correct places on the conning tower.
