help - Client 2018 + date - doubt

[matheus00123]

Hello,

I'm coming back now, and as always has changed a lot in ragnarok, I've been looking at the 2018 clients and found it 
interesting, but I saw that it was discontinued.
But I wanted to know, which client do I use, what date should I use RoZero (data.grf + data0.grf) 
or kRO (rdata.grf + data.grf)?

Thanks in advance.

Sorry for my English, I'm Brazilian and I'm using google translator.

RoZero isn't supported by rAthena. You should use kRO.
