As 2016 got few errors in nemo patching, 2015-12-16aRagexe client i think is best option to be try.. might not be the newest client.. but somehow this is the newest for 2015 client.. i noticed in hercules /src/map/packets.h, already support this 2015-12-16aRagexe client..
For me 2016 client, although can be implement on the emu, but, due to the constrain of nemo patcher fail & got errors in patching, might be resulting the client is not reliable & stable to be implement on the emu.. beside that, if we go to nemo github, it had been a while since last commit, 29 May 2016.. in easier words, i might say 2016 client quite too far to be use... so 2015-12-16aRagexe client maybe the best option of the newest client with working nemo patching...
there is 2 2016 client, (2016-02-03aRagexeRE & 2016-12-28aRagexeRE). i've try to patch both client using nemo patcher, got few errors.. below is the screenshot of the errors.. but, if u guys avoid using those patch, i think it is OK. but, seems to be the client is not fully patch..
