You need to use Heroes client, with the patches. It's as easy as heroes to set up, however I think the set on here doesn't work or at least has a work around in the source.
Not to mention there completely chinese (Chronicles uses AppleM2 Engine)
Your best bet is to ask one of the team members of Chronicles to release a binary set of an much older source (AceM2).
Good luck, personally i would follow C#
