Please view this only on a real c64 or an emulator with a freesync or 50hz display, it makes heavy use of frame updates with offsets and shifting to generate the video frames. uneven updates will destroy the quality further. For this reason same applies to youtube video footage that is just recorded from an emulator and frames decimated by the conversion

quick notes as follows

16khz sample playback with a more optimised ssdpcm2 audio decompressor. The whole song is there with not a single piece missed out
50fps video update (not partial). frame sizes range from 240bytes to 1k a frame. As the source video content was 25fps, i am using frame trailing and offset changes at 50fps. (There are some sequences later on that are running at individual frames per frame update

i have prepared a video using frame blending here for a rough preview. On a crt screen it will flicker more, but frame updates should be stable as well.

8580 sid recommended (although may produce worse audio on some 8580's too). 6581 not recommended and will vary widely in quality

The whole demo is packed to a 1mb easyflash cart.
