PvP .66

Under new GS everyone is using (.66) there is a PvP error wich if we analyse its on the PK Check fuction:

Code:

004B9B9F . 8B55 08 MOV EDX,DWORD PTR SS:[EBP+8] 004B9BA2 . 0FBF82 A600000>MOVSX EAX,WORD PTR DS:[EDX+A6] 004B9BA9 . 83F8 05 CMP EAX,5 004B9BAC . 7F 07 JG SHORT GameServ.004B9BB5 004B9BAE > 33C0 XOR EAX,EAX 004B9BB0 . E9 26040000 JMP GameServ.004B9FDB 004B9BB5 >^E9 9EFEFFFF JMP GameServ.004B9A58 004B9BBA > 90 NOP 004B9BBB . 90 NOP 004B9BBC . 52 PUSH EDX 004B9BBD . E8 D8B1F4FF CALL GameServ.00404D9A

Well seems some one do a jump to his own code... lets see:

Code:

004B9A58 > 8B4D 08 MOV ECX,DWORD PTR SS:[EBP+8] 004B9A5B . 51 PUSH ECX 004B9A5C . 8B4D 0C MOV ECX,DWORD PTR SS:[EBP+C] 004B9A5F . 51 PUSH ECX 004B9A60 . 90 NOP 004B9A61 . 90 NOP 004B9A62 . 90 NOP 004B9A63 . 90 NOP 004B9A64 . 90 NOP 004B9A65 . 83F8 00 CMP EAX,0 004B9A68 . 0F85 64050000 JNZ GameServ.004B9FD2 004B9A6E . 8B55 0C MOV EDX,DWORD PTR SS:[EBP+C] 004B9A71 . 52 PUSH EDX 004B9A72 . 8B45 08 MOV EAX,DWORD PTR SS:[EBP+8] 004B9A75 . E9 40010000 JMP GameServ.004B9BBA

This is stupid, the guy who did this on the public GS dont wanted to make PvP work or he just try to do some edit job and he mess it up.

So lets put the fix so simple has this:

Code:

004B9BB5 ^E9 B4FEFFFF JMP GameServ.004B9A6E 004B9BBA > 90 NOP 004B9BBB . 90 NOP 004B9BBC 50 PUSH EAX

That its how it should get for a fast fix, please feel free to ask or tell any problem about this bug.

YOU NEED TO DO THIS WITH OLLYDBG

1.- Open Ollydbg with GS .66
2.- Press CTRL+G and put 004B9BB5
3.- go under JMP line, press SPACE BAR and place this JMP 004B9A6E
4.- go under PUSH EDX line, press SPACE BAR and place this PUSH EAX

ok simple and fast, enjoy.

Its a fast fix, of course you can restore to normal code of how it should be, but remember not everyone knows how do it, here fix for people think they pro:

Code:

004B9BAC . /7F 07 JG SHORT GameServ.004B9BB5 004B9BAE > |33C0 XOR EAX,EAX 004B9BB0 . |E9 26040000 JMP GameServ.004B9FDB 004B9BB5 \8B55 0C MOV EDX,DWORD PTR SS:[EBP+C] 004B9BB8 52 PUSH EDX 004B9BB9 8B45 08 MOV EAX,DWORD PTR SS:[EBP+8] 004B9BBC 50 PUSH EAX 004B9BBD . E8 D8B1F4FF CALL GameServ.00404D9A

No big difference...

Now if you want to be more "pro" hahaha do this then:

Code:

004B9B9F . 8B55 08 MOV EDX,DWORD PTR SS:[EBP+8] 004B9BA2 . 0FBF82 A6000000 MOVSX EAX,WORD PTR DS:[EDX+A6] 004B9BA9 . 83F8 05 CMP EAX,5 004B9BAC . 7F 07 JG SHORT GameServ.004B9BB5 004B9BAE > 33C0 XOR EAX,EAX 004B9BB0 . E9 26040000 JMP GameServ.004B9FDB 004B9BB5 8B45 0C MOV EAX,DWORD PTR SS:[EBP+C] 004B9BB8 50 PUSH EAX 004B9BB9 52 PUSH EDX 004B9BBA E8 DBB1F4FF CALL GameServ.00404D9A

Assuming for get into that part of code EDX its equal to [EBP+8] you dont need to mov it again, so you just push it... you got some free lines and make the execution more faster (of course you wont even note it).

Everything depends of how people want the fix, noob way, normal way, pro way, but anyway its a fix... :P
