[WoW]: Cross faction talk

[bobbysing]

Hello,

today I found a nice way to talk in every available game-language by patching a single byte! ( server-side checks missing! )

[20:43:25]:  0x00490FEA -> Language_Restriction

or

<Pattern desc="Language_Restriction" pattern="\x85\xC0\x75\x20\x68\x20\x02\x00\x00" mask="xxxxxxxxx">
    <Add value="2"/>
</Pattern> 

00490FE2  |. 50             PUSH EAX
00490FE3  |. E8 E8B31400    CALL Wow.005DC3D0                        ;  can he speak the language ?
00490FE8  |. 85C0           TEST EAX,EAX
00490FEA  |. 75 20          JNZ SHORT Wow.0049100C                   ;  no!
00490FEC  |. 68 20020000    PUSH 220                                 ; /Arg1 = 00000220
00490FF1  |. E8 FA730000    CALL Wow.004983F0                        ; \Wow.004983F0 

Then you can change the first byte at 0x00490FEA to 0xEB in order to disable the language check.

This is how you can send the chat messages then:

/script SendChatMessage( "Kynox is leeeeet!", "YELL", "DRACONIC" ); 

PS: This bug has already been reported by me and may stop working in the next time

Have fun!

Tested and confirmed working on live servers.
