Marlin 2.0.x nd mks gen 13

Hi I have a homebuilt printer and have a problem with babystepping/ auto bed leveling, and fade height.I am running marlin 1.1.9bugfix and the babystepping feature does not work correctly.I tried to upgrade to marlin 2.0.X and this will not compile. I loaded my config and config.adv files into 2.0.X (So the mother board selection will be correct. MKS Gen 13) and when I tried to compile I get an “unable to compile with arduino/ramps board” error. My config file work fine on marlin 1.1.9. Any one know what gives here? Also, does any one know if the babystepping issue is fixed in 2.0.X?
