This is supposed to be a tutorial how to update packet.dll after a tibia client update.
There is two memory addresses that needs to be updated:
MEMORY_ADDRESS_Send_Pointer
-Use olly and load tibia
-Select: Search For -> All intermodular calls
-Find WS2_32.send
-Double click on the call to see the address we need
MEMORY_ADDRESS_Socket_Pointer
-Use olly and load tibia
-Set a breakpoint on WS2_32.send and run and login tibia until it breaks
-In olly step over the breakpoint to the return call right after and step into it
-Some lines before the current EIP there is a line with MOV ECX,DWORD PTR DS:[ADDRESS]
-The address is what we need
The source is in MASM so the masm compiler is needed (get it for free from: www.masm32.com), I use following command lines to compile it:
When you compile it yourself there are somethings you need to change.Code:ml /c /coff /Cp c:\masm32\code\packet\packet.asm PoLink /dll /export:SendPacket /export:XTEA /NOLOGO /MERGE:.data=.text /MERGE:.rdata=.text /MERGE:.reloc=.text /entry:DllEntry packet.obj
First the path to ml.exe and PoLink.exe (you can use link.exe instead of PoLonk.exe if you wish).
Second is the path to the source.
I have zipped all files needed, including pics, source and examples. Its for an old version, 7.8 I guess.
Dark Pallys: I just disabled smilies in text so it wouldn't be confusing
