400' is correct. There is no patch.
Using a hex editor is possible to edit the various depths. Kim Ronhof, myself and a couple others put a lot of work into deconstructing the various files.
What you want is in Subs.dat:
Quote:
"The Subs.dat file starts with byte 09 Then it lists the different Sub types.
Each listing is 32 bytes long and the ending last 4 bytes hold the address where the Data for the specific Subtype data is."
"The specific Sub type data are each 1704 bytes long.
And start as follows:
........... Dec .......... Hex
Type ...... Address ... Low Byte ...High byte
S-Class ... 289 ....... 21 01 ...... 00 00
Barracuda . 1993 ...... C9 07 ...... 00 00
Narwhale .. 3697 ...... 71 0E ...... 00 00
P-Class ... 5401 ...... 19 15 ...... 00 00
Salmon..... 7105 ...... C1 1B ...... 00 00
T-Class ... 8809 ...... 69 22 ...... 00 00
Gato ...... 10513 ..... 11 29 ...... 00 00
Balao ..... 12217 ..... B9 2F ...... 00 00
Tench ..... 13921 ..... 61 36 ...... 00 00
Then:
TestDepth - PeriscopDepth - Radar depth
00000449:C8 00 00 00 30 00 00 00 24 00 00 00 37 00 00 00
00005561:FA 00 00 00 37 00 00 00 28 00 00 00 3E 00 00 00
00007265:00 01 00 00 37 00 00 00 28 00 00 00 3E 00 00 00
00010673:2C 01 00 00 3C 00 00 00 2D 00 00 00 44 00 00 00

If you can use a Hex editor. Having conversion tables also makes it easier.
Frhed worked for me.
Anyway, I'm pretty sure 400' is the WWII BALAO class Test depth. Maybe it was changed after the war. Don't know.
Happy Hunting!
