Compiling How do I compile OTHire 7.72 to 7.60?

[Kodis]

Hey there.
As the title says I would like to compile the OTHire 7.72 to work with 7.60
Unfortunately I have no idea what I have to change in the sources.
I have tried to change the protocol.h to

#define CLIENT_VERSION_MIN 760
#define CLIENT_VERSION_MAX 760

also I tried to change definition.h to

#define OTSERV_CLIENT_VERSION "7.60"

But that's as I though not enough so I am pretty much not able to do it without help.
Is it that hard to get to work with 7.6?

Regards
