Booty Bay WoW Exploit Community

now when you set the item price to 28634g
the fees will only be 13s27c

why?
One of my friend familiar with programme explain to me by this:

(well I dont understand this shit too I just know it works and copy and paste it here)

the model answer should be: 28633g11s54c

because 286331154 * 15 = 4294967310

change it to hexadecimal: 10000000E
it become 9 digits, for a 32-bit system the 9digit will overflow

and the fees will be 0 T 14/100 = 0

and in the 5%AH you set the price 85899g34s60c will have the same effect

so when you set the price to 28634g in a neutral AH the fees should be 4295g10s
but because the limit of the fees is 4294g96s72.96c, the fees will be overflow and become 13s27c

sorry for my sucking english
the exploits is quite useless if you dont have a horde and alliance account

but the “overflow concept” maybe useful in another way so I would like to share it out

EDIT: quote from Killerpet who explain better than me

——————————-
Proof:
Auctioneer_Cut = AP * 15 / 100

(splitting it up as gold silver copper)
start with
28634g 00s 00c (or 1111 33A0 hex)

First multiply the number by 15
28634g 00s 00c * 15 = 429510g 00s 00c (or 1 0002 0660 hex)

now assuming op is correct and there is an overflow this will change to 0002 0660 hex (or 13g 27s 04c)

Now divide it by 100
13g 27s 04c / 100 = 0g 13s 27c

Fee = 13s 27c

Alternate solution:
Auctioneer_Cut = AP / 100 * 15

start with
28634g 00s 00c (or 1111 33A0 hex)

First divide it by 100
286g 34s 00c (or 002B B128 hex)

Here there is no overflow

Now when you multiply it by 15
286g 34s 00c * 15 = 4295g 10s 00c

——————————–
If this works then you would need an auction of 42951g 00s 00c for roughly the same result on the normal AH

Proof:
Auctioneer_Cut = AP * 10 / 100

(splitting it up as gold silver copper)
start with
42951g 00s 00c (or 1999 CD70 hex)

First multiply the number by 10
42951g 00s 00c * 10 = 429510g 00s 00c (or 1 0002 0660 hex)

now assuming op is correct and there is an overflow this will change to 0002 0660 hex (or 13g 27s 04c)

Now divide it by 100
13g 27s 04c / 100 = 0g 13s 27c

Fee = 13s 27c
