Master Versions

[sli]

This came up on IRC the other day. Anyone wanna help find where master versions are stored in the client? (If you even THINK "sclientinfo.xml," this thread is way above your head.)

[Bibian]

omg its not in sclientinfo.xml? >_<

anyway, im not sure but aren't private servers able to modify this value in the client somehow?
We should look at how they do it...

We can probably also find it by finding various packet code in disassembly.

[Bibian]

So who wants to attempt to find this?

All ready old thing.
Client has an a table, witch is something like this:
Version Range, Master version Range.

To be true, it's just a switch-case statement there.
It can be easily found, when you hook the place where login packet is made.

Yea seems like masterversion (aka region?) is derived from the combination of 2 tables.
some extra information

[iamanoob]

would this narrow the correct serverType?
if they can do it, we can crack it.
(exclude me, im a noob...)
