A nice graphical Encryption Removal tool is always good to have

Confirmed that UOCH does a great job of removing the 100% stamina check from clients in the Felucca realm.
This allows your Pushthrough hook to run.... BIG HOORAY!!!! I've been wanting this for ages.

I did a hex check on my patched client. It has one byte changed from C0 to D0.

Are you sure you checked 'Remove the Stamina', and are you sure you are using the right client?
I had no problems with it!

Terciob, send me that client 6.0.1.7 with PM I will take a look at it. And as Damien said make sure you have the Stamina Check Removal button checked.

Also make sure you aren't using a pushthrough hook on the realm that it's blocking on. hehe

Damien, yea, is checked =)
MuadDib, no pushthrough hook running.

Found the error in UOCH, Reuploaded files in first post.

Works fine..
Goob job!

So, can you enable check box for remove encryption ?
Client using Razor assistant (www.runuo.com/razor) cannot logon (using or not "Patch client encryption" option in razor):

Quote:

Client#8: Unexpected message type e8, 26 bytes (IP:10.1.1.3, Account:None)
0000: e8 48 c0 2c 3c ae 07 a3 ec 60 9d 93 b7 e8 26 d7 .H.,<... .`....&.
0010: 17 37 71 cd 48 d0 92 34 81 29 .7q.H..4 .)......

Thanks.

Changed the "Remove Encryption" button to not be disabled, so you can turn it on / off.

COuld someone please elaborate what exactly is the issue with the stamina?

Tomi · **Joined:** Tue Feb 21, 2006 5:08 pm **Posts:** 306

Normally the client is checking that you have 100% stamina to push through another playing character on Felucca Facet.

But with the patch in UOCH, it removes that check and you can control what happen when pushing through another character with the pushthrough hook. ( Normally this is working for every other Facet than Felucca, but not Felucca )

- Added Weather Packet Message removal. ( Stops client from sending the messages with packet 0x65 for example "A storm is brewing." )

UOCH removes the UO:SA Classic client encryptions, no changes made.

Yukiko · **Posted:** Sat Aug 22, 2009 4:58 pm

Can this be modified to remove the multiple UO client check so's we can run more than one client? This would be most helpful when testing various stuff on a shard.

Yukiko · **Posted:** Sat Aug 22, 2009 6:23 pm

Also, I don't know if this is a POL or client encryption issue but the latest client version 6.0.14.2 Patch 79 locks up after shard selection. UOCH reports the following in the log:

Code: Select all: Patching... LCrypt: New crypt sig @1FAA5 LCrypt: Patched @1FAA5 GCrypt: Could not find blowfish encryption FFFFFFFF FFFFFFFF GCrypt: Found New twofish @1FB87 GCrypt: Patched @1FB87 GCrypt: Found New MD5 @20DEE GDecrypt: Sig @20DEE patched @10E3BD New UOCH client: "C:\Programs (x86)\Ultima Online\UOCH_n0p3_Client01.exe" Time elapsed during patching: 203ms

Still it locks up. Any ideas?

its a packet 0xB9 issue, changed from being 3 bytes to 5 bytes

You have to wait for the next core release:
pol98.2
07-15-2009 Turley
Added Support for client 6.0.14.2 and latest UOKR (this change breaks every older UOKR) packet 0xB9 has now a length of 5
