T.M.R has (kind of) billed this intro as a 'sequel of sorts' to a Cosine entry to the same competition from 2014 and he explains that while it may look simple, the code...
"jumps through quite a few hoops in order to make an otherwise silly technique work, using unrolled code and waiting for the C64's raster register to change before updating over 184 scanlines. There's further unrolled code updating those routines as well to animate them so this intro decrunches from $0400 to just shy of $3fff."
The music was originally written (along with a couple of other unfinished efforts) for the CSDb 'Crack Intro Music Competition 2017', but ended up not being used because it was too long and didn't work well on a 6581 SID; it was written with 8580 in mind. It has been finished and used here instead, having been given the name 'Bas Braster' which is Welsh for... well, just look it up...
The intro can be downloaded from the Cosine website here or it's compo entry page on CSDb here...
You can also download the intro direct from this blog, with the .zip file including not only the demo on a .d64 image, but the music as a .sid file to run through SIDPlay or similar and the music in .sng format which can be loaded into Goattracker, the utility in which it was composed. Just click here...
T.M.R has also recorded a video of the intro in action and uploaded it to YouTube. The player should appear below, but if not watch it here...
