This picture was created for a homebrew version of the classic arcade. It uses C64 Multicolor Mode plus border sprites.

Restrictions: 

Preset 16 color palette, resolution 160x200px (plus border cut to the picture dimensions here), double-wide pixels
The screen is devided in grid by 4x8px size blocks
One background color fix for the whole screen, 3 color free of choice per block.

Sprites are also set to multicolor, so that is double-wide pixels, size is 12x21px for each object. 3 colors + 1 transparent are set in this mode, though only one is selectable, others are fixed. There is a maximum of 8 sprites per rasterline.
