@Francois,

I don't know if you are using GitHub. Please try this to alter the scan lines:
from this:

            WriteCmdData(0x01, GS | SS_v | (_lcd_ID == 0x0139 ? 0x27 : 0x28));       // set Driver Output Control

replace with this:

            WriteCmdData(0x01, GS | SS_v | (_lcd_ID == 0x0139 ? 0x28 : 0x28));       // set Driver Output Control

The S6D0139 Vertical Scroll works differently. The datasheet is unclear.
from this:

    case 0x0139:
#if 0                                   //disable scroll
        WriteCmdData(0x42, sea);        //SEA
        WriteCmdData(0x43, top);        //SSA
        WriteCmdData(0x41, vsp - top);  //VL# check vsp
#endif
        break;

to this:

    case 0x0139:
#if 1                                   //enable scroll
        WriteCmdData(0x42, sea);        //SEA
        WriteCmdData(0x43, top);        //SSA
        WriteCmdData(0x41, vsp - top);  //VL# check vsp
#endif
        break;

You may need to uncomment VLE1:

//            0x0007, 0x0217,     //Display Control: VLE1=1, SPT=0, GON=1, REV=1, D=3
        };
        init_table16(S6D0139_regValues, sizeof(S6D0139_regValues));

I am assuming you know how to edit a file. Life is much simpler if you could say whether you have a GitHub client.

David.
