Compiling Learning, How do I downgrade TFS 1.1?

[The Amrath]

Hello otland, I'm trying to learn how to work with C++ and I've now started to experimenting how to change client version on TFS.

From what I understand TFS comes from OTLand so I come here to seek for the support.
ofc I will share my experience with others.

So.. now I'm using a TFS 1.1 for client 8.60 and I want to downgrade that to 7.7 for fun mostly.

I've changed these in definitions.h
#define CLIENT_VERSION_MIN 772
#define CLIENT_VERSION_MAX 772

And then I'm unsure what need to be changed, and in which files.

Could someone give me any clues what I need to edit?

Thanks in advance guys!

btw, don't mind items/ingame stuffs.
I just want to understand what edits need to made in order to just login.

I've been able to load character list, get messages of banishments etc, but as soon I login for real I get debug.
I've removed the part there stamina and addons are sent to the client during game but that's no enough

So I must have missed something
