Okay, just to clear things.. I'm not saying it's possible to change the "stall carpet" to a Blacksmith NPC. I'm saying it's possible to change the MODEL of the carpet to something else, like a Blacksmith. The Blacksmith would still act like your shop; if someone clicks it, your shop will open.
I have done it, and it's possible with a proxy. I just figured it'd be doable through asm too.

If this works then I still wonder why on earth they would request such info from the client :|

Yea, I know, I was like wtf too, when I did it the first time.
As far as I remember it was a "06" at the end of the "set-up-a-stall-packet" that determined the "carpet model".

It wouldn't even be hard to change what a certain packet contains via asm; Only thing you need to know is the packet id, look where the packet is constructed and hook on it. If it works, good. I doubt it will though, it can't have been coded that poorly.

Code:
18 00 F2 03 F9 A8 EB 00 77 32 16 00 DC 00 0C 01 DC 00 0C [SIZE="4"][COLOR="Red"]01 06[/COLOR][/SIZE] 00 6F 00
This was the thing that controlled the "carpet model" in the set-up-a-stall-packet, before they changed encryptions at least. Change it 1E 24 and you'd have (according to what I remember) one of those sandmonster NPCs (or well, the model of it).
I know all this is probably a bit off-topic, but I was just thinking that *M*, or some other person, could make this via asm.

Actually you could edit the client to call the correct functions to create encrypt and send a packet (though you'd only need to worry about calling the create packet function) in order to send any packet you desire.
I have to ask, how much have you actually done? Have you ever played around with packet data? Because I have and I'm sure *M* and IAmHawtness have.
In other news (to you at least) it used to be possible to spawn npcs anywhere before tq implemented a range check in order to upgrade, repair, buy and sell...all that would happen is you could spawn an npc client side and use it to force the client to create and send packets itself for what you wanted to do (or you could send the raw ackets yourself).

Edit: Posted another picture to prove that this isn't client sided
Edit2:
LOL, I did it . Feel free to visit me and check it out yourself .
I ******* love asm
For anyone who would like to try this, PM me or something  . Or find out how to do it like I did.

haha it's been a long time since I've been able to place the carpet anywhere  Thought they fixed that so it had to be in front of a flag...I could still open it in front of any flag though as long I sat at another one....COOL! gratz.

Haha, this is awesome. I found the ID of the GuildWar Pole (2B2), it should create some attention if I placed it near LoveStone or something in Market

Umm yea so you can change the client, what good is that anyway? Using those shops etc will still be server side and not allow you to do things.

Server side, exactly. That's why it's funny, other people see your shop as, for example, a Guild War Pole, and when they click it, my shop opens.
It's just an attention drawer. Being able to place the shop wherever you want is fun too  .

That is rather funny, I'm going to do some tests tomorrow whether I can create a custom command to spawn them. :P Only thing I need to know is how to get a string splitted by certain delimiter. (So I can create a command like /spawn <ID> :P, I can read the coordinates of player from memory)

Sorry for double posting.
At address 004E6F26 for latest client it starts some sort of item processor, basically you can make it to output whenever you get a meteor/dragonball or other drops.
Code:
004E708D |> 3D 009A1000 CMP EAX,109A00; Check whether id is 1088000 (Dragonball)
004E7092 |. 0F84 8B000000 JE 004E7123
004E7098 |. 3D 019A1000 CMP EAX,109A01 ; Check whether id is 1088001 (Meteor)
004E709D 0F84 2E920400 JE 004E7123
Basically you can make the Conquer.exe to tell whenever a meteor or dragonball dropped, here's an example of how to make the client trigger on meteor drop
Code:
005302D1 {
This is the code to output a message on screen.
//Bytes
6A 00
6A 00
68 0000FF00
68 D5070000
B9 48945700
E8 2F43F5FF
E9 306EFBFF
//Asm code
005302D1 6A 00 PUSH 0
005302D3 6A 00 PUSH 0
005302D5 68 0000FF00 PUSH 0FF0000
005302DA 68 D5070000 PUSH 7D5
005302DF 68 70905600 PUSH OFFSET Conquer.00569070 ; ASCII "Meteor dropped!"
005302E4 B9 48945700 MOV ECX,OFFSET Conquer.00579448
005302E9 E8 2F43F5FF CALL 0048461D
005302EE ^ E9 306EFBFF JMP 004E7123
};
00569070 {
//Bytes
4D 65 74 65 6F 72 20 64 72 6F 70 70 65 64 21 ; "Meteor Dropped!" (We add this to Conquer.exe data)
};
004E709D {
//Bytes
0F84 2E920400
//Asm code
004E709D /0F84 2E920400 JE 005302D1
}
Outside the brackets is the address where to write, inside are the code bytes.
Feel free to ask about this.
