Hey guys, I'd like some help converting my gamemode from y_ini to mysql (latest version). Seems very difficult for me cause there are many features and I can't find any stock that saves players data, only callbacks (onplayerofflinelogib,onplayerofflinesave etc.) What's the best way to convert it? And where I should start first? Login/register system, saving data or what?
Any good tutorial appreciated or some instructions/help.

P.S please do not tell me to start the gamemode from scratch (obviously I'm using edited one)
