This is a demo of what can be easily achieved with SAGA chipset from AC68080.

VampireDemo2D uses Picasso96 system to open and initialize screen then writes
directly into video buffer by installing it's own triple buffer. Graphics are
prepared to target a 16Bit R5G6B5 screen.

Sources are included for reference.
