Re: LastChaos Wind0ws Server files DEVELOPMENT

@ s0m3one and whomever else, I searched my archive database and these are the only LC clients I have, would any interest you for testing?

Also, do we have a close idea of the date of the server files and what region it was compiled for?

AquaLung

.

The server files and database are from Korea (the text printed out on the server files is Korean). They are probably around late 2008, early 2009 server files.

Also could you post download links to every client in your database that starts with LcInstall_xxx.exe Them should be the official Korean clients.

Re: LastChaos Wind0ws Server files DEVELOPMENT

hm mindsharing...

i think its better to fix this bug on server and not on client, cause we have the same bug vom 07xxx up to the "1st-post-client" if we fix an spezific client we still have the "bug" (yes not even an bug only wrong client) but we change the "bug" in the server we can maybe use rly client so far...

Try this:

goto offset 6BAA and replace '0F 84' with '90 E9'

Re: LastChaos Wind0ws Server files DEVELOPMENT

Thanks
I thought it was about the Engine.dll

Re: LastChaos Wind0ws Server files DEVELOPMENT

hey guys i was able to fix it running the file in the bin folder, i even updated the database with that item.sql and also have a few friends playing from their house on my server, it worked great for like 3 hours now every time we log into game mysql crashed instantly for some reason idk why only thing that i changed was levels and added stat points, any idea?

Re: LastChaos Wind0ws Server files DEVELOPMENT

Hmm ok, i found something interesting which i wish i didn't found.
So i took the un-encrypted gameserver and sniffed the packet that the server sends to summon another player on the screen.
I compared that packet with the same packet i use in my emulator which uses a recent client.

What i found is that, (only showing the beginning of the packet since thats all that matters for now)

td.AddByte(0x07);
td.AddByte(0x01);
td.AddByte(0x00);
[COLOR=DarkOrange]td.AddInt32(CharID);[/COLOR]

Take a look at the last part, where it tells what equipment the character to display is wearing.
As u can see there is nothing that defines which helmet a character is wearing. this is because in the old days helmets were never displayed.
Helmets were seen for the first time i think around the release of the 97 armor. (maybe earlyer for costumes but i forgot since its a long time ago)

So i think we are infact searching for to new clients.

Given that dratan siege is working i think that we should look for a client that has dratan siege and the tomb of theo. (maybe strayana but doesn't have to) And the highest armor obtainable is 85-87. if it has the strayana caves, then its to new.

The 2009 client doesn't have helmets. So the client is gotta be around the 2008 era to keep dratan siege.

Probably the closest were going to get out of the USA clients. We still need to check the Korean clients. Them are most important.

Re: LastChaos Wind0ws Server files DEVELOPMENT

As u can see there is nothing that defines which helmet a character is wearing.

its imposible do change the sending packed by server with helmed information?
sure, server sends instandly "no helmed" but right packedsize, only an dummy cause i already think we should make the server campatiple with newer clients and don´t search an much older
if we have an newer cilient update shoult be easy with new content like items, sure its also easy with an older but much easyer with an newer

and update server with items, mobs, skills its pretty easy

Sadly i don't have any knowledge in ASM.
If i had then i would be much more actively working on these files.
For now we have to depend on people like GHOST107and s0m3one which are doing awesome work and lets try to support them in any way possible.

Re: LastChaos Wind0ws Server files DEVELOPMENT

1)open engine.dll with PEiD
2)start the pluggin KANAL
3)Look at the DES [keyscroll] [char]
4)copy the addrees from the second reference to

5)open engine.dll with olly debugger
6)goto adress of the reference
7)scroll down 2 RETN
8)change the code with this

104FEBD0  /$  51            PUSH ECX
104FEBD1  |.  8B4C24 08     MOV ECX,DWORD PTR SS:[ESP+8]

Second Method:
Open Engine.dll with an Hex Editor, search for 518B4C2408 hex values, copy the offset to the paper.

Open Engine.dll with OllyDbg Goto->expression, Calculate the address (10001000-1000+offset), use the code above.

Edit: Yes you cant debug crap with olly under a 64bit OS <_<
