Michael started a project in 2010 to enhance the graphics of the Commodore VIC-20. The new graphics mode requires a hardware modification of the VIC-20. The normal RAM is expanded from 5 kB to 8kB and the new colour RAM is 16 times bigger than the original. Recently Michael updated the conversion software and introduced gamma-correction which improves the quality of the converted pictures. You can read all about the VFLI system on the Denial forum.
