I managed to install a rather modern local RO client & server with cats and stuff. But now I want to have also a server with old mechanics (no renewal, no 3rd jobs, but first version of Laboratory). 1) So I guess I need not current kRO client but some old one. Am I right? 2) What date of Ragexe.exe do I need? Does NEMO properly works with it? 3) And what about rAthena itself? Does modern HEAD-release support old server emulation? Or I need to switch to older revision/branch? Sorry for a probably noob questions. Sorry if I chose wrong subforum - was really confused where should I post it.
