Rambo Board for my Prusa wont work with LCD please help

so basically like the title says i cant get it to work, but i noticed one thing that is very odd to me

how come i cant find this in my firmware?

‪#‎define‬ MOTHERBOARD 33

is this line not in marlin anymore? i keep downloading different releases of marlin and i cant seem to find this in any version i find online
i only see this

// The following define selects which electronics board you have.
// Please choose the name from boards.h that matches your setup
‪#‎ifndef‬ MOTHERBOARD
#define MOTHERBOARD BOARD_RAMPS_13_EFB
‪#‎endif‬

also please dont just post links to wiki tutorials, i have already found them and tried to follow them. I really need someone who has a know good version of firmware for a prusa that has a rambo board with a reprap discount smart controller, or full graphics display, i have both of those here

New Motherboards definitions have been changed from numbers to names, and you must use the name as parts of the code looks for the name

Also type 33 is ramps... you need BOARD_RAMBO which is 301


Re the LCD you have installed the "RAMBo Arduino Plugin" ?

These are required. The standard mega doesn’t have have some of the pins that are used on rambo defined, specificity it uses these pins for the LCD.


I would have linked to this information in the wiki... but you have already found them....

Good luck.
