how to get manual download link from game updater ?

[chivien]

im updating some online game thru the game launcher but it's inconvenient so i want to download the patch files manually (example : elsword or something)
how do i get the direct link ?

example im downloading patch001.abc from the game launcher, how do i extract the direct link ?

You could use a network sniffer like wireshark to see if and which HTTP Requests are sent (there you'll see the "direct links"). In the unlikely case that a proprietary protocol is used instead of HTTP, it would get much more complicated.

You could also try this approach:

1) open the binary with ollydbg
2) take a look at all referenced strings (just copy the whole table to any texteditor you like and STRF+F your way through it )

The URL is hardcoded in the referenced string table and should contain %s printf statements that tell you further informations about the structure of each update link.

i'll try this ollydbg later but it looks complicated

here is the screenshot of me running the updater and wireshark, any idea what to do ?i tried ctrl + F and find reactor.exe (the updater process) but nothing found

You can attach a debugger to the program

You should try to use Fiddler instead of Wireshark. Wireshark shows way too much request you don't need if you don't apply the right filters. Fiddler will show you the name of the process that sent the request, and only the http ones, it'll be easier to find the one you're looking for.

i used cheat engine to attach a debugger to the game updater process but nothing happened

i dragged the process filter to the game updater (reactor), the log show "09:02:30:6447 Set to show traffic from only 'reactor:1220' HWND=0x204ee"

what do i do next ? nothing new showed

that's the expected behavior
putting in the cable of a microwave doesn't give you warm food. You actually have to read the manual and use it...
