This program is a help for C64 multicolor graphics paint programs that displays the coordinates, such as Advanced Art Studio or Wigmore Artist 64. You can use it on your phone while painting on your C64 or C128. Press the green flag to start. Press "(0,0) is upper left corner" to change coordinate system used for different programs. Adv Art Studio uses upper left while Artist 64 uses bottom left corner. In case you have no clue what this helper app does: In C64 multicolor mode, for every 4x8 pixel square on the screen, only three different colors plus background color can be used. So, by entering the pixel coordinates of where you are currently working (in magnify mode for example), this helper app will show you the position of that pixel in the 4x8 square that it belongs to.
