[ASM] 'Real' GM Shop

[Disconnect1]

Well this is a little code that i allways i wanted to do :D
This is allows to enter only the GM.
This was tested on 0.97d and works for all versions!
First you must choose an NPC seller (ShopX.txt), i`ve choose Shop3.txt (Lorencia Peddler) and then hook it in NpcTalk

The most important code is:

Mov Edx, DWord Ptr Ds:[Eax + 174H]

174 means GM CtlCode, in every version differs, you can simply find it in PChatProc or CGMMng::ManagementProc.
For 1.00.18 is 1C8

So here it is

.Const
gObjIsConnected DD 00401AA0H
MsgOutput DD 00402BBCH

.Data?

.Data
IsGmShopBuff DB 1 Dup(0)
Section DB "Common", 0
Ini1 DB "MBTIsGMShop", 0
IniFile DB ".\MBT_Common.ini", 0
IsGMMsg DB "Welcome to GM Shop!", 0
NotGMMsg DB "Users are not allowed to enter this shop.", 0


.Code
DllEntry Proc hInstDLL:HINSTANCE, reason:DWord, reserved1:DWord
	Mov Eax, TRUE
	Ret
DllEntry EndP

IniOptions Proc
	Invoke GetPrivateProfileInt, Addr Section, Addr Ini1, 0, Addr IniFile
	Mov DWord Ptr Ds:[IsGmShopBuff], Eax
	Ret
IniOptions EndP

GMShop Proc
	Local IsGM:DWord
	Local UserID:DWord
	Push Ebx
	Push Esi
	Push Edi
	.If Byte Ptr Ds:[IsGmShopBuff] != 1
		Jmp Finish
	.EndIf
 	Mov Eax, DWord Ptr Ss:[Ebp + 0CH]
 	Mov Ecx, DWord Ptr Ds:[Eax]
 	Mov UserID, Ecx
	Push Ecx
 	Call gObjIsConnected
 	Add Esp, 4
 	Test Eax, Eax
 	Je Finish
	Mov Eax, DWord Ptr Ss:[Ebp + 0CH]
 	Mov Edx, DWord Ptr Ds:[Eax + 174H]
 	Mov IsGM, Edx
 	Add Edx, 1
	.If Edx == 1
OnlyGM:
	Lea Eax, NotGMMsg
	Push Eax
	Mov Edx, UserID
	Push Edx
	Call MsgOutput
	Add Esp, 0CH
	Jmp Finish
	.EndIf
WelcomeGM:
	Lea Eax, IsGMMsg
	Push Eax
	Mov Edx, UserID
	Push Edx
	Call MsgOutput
	Add Esp, 0CH
Finish:
	Pop Edi
	Pop Esi
	Pop Ebx
	Mov Esp, Ebp
	Pop Ebp
	Retn
GMShop EndP

End DllEntry
