Change current menu for a six axis robot

  3d-printing, arduino, c++

I used MKS Robin v2.4 (+ its special TFT )for my six axis robot with marlin 2.0 FW and change 320*240 UI of marlin . ( this file : Marlinsrclcdtftui_320x240.cpp ) But now I can’t purchase mks robin mainboard in IRAN and It’s hard to buy . so I decided to use MKS GEN V1.4 + MKS TFT32_L V4.0 . now my problem is how to change menu functions (Gcode of each menu item ) and text and build my UI .
can anyone help me ?
