Website update: I've updated my favourite SIDs playlist at https://fairysvoice.net/playlists/ to include a large handful of recent finds over the past year or two.
Start listening to a SID.
It's a remix of a track called "StillPlayingMario.nsf"
I search for the NSF original.
There is no original.
I love playing the High Voltage SID Collection on shuffle, discovering some interesting mid-2000s chiptune, and then, as soon as it finishes, immediately getting Shave And A Haircut on sawtooth wave
*clicks on a SID file called "Paradise Lost"* Man, they were doing Commodore 64 game adaptations of everything in the 80s, huh
