I am looking for some legal royalty free music, possibly sound effects. Even if it requires a purchase. I'm looking for tracks that sound like early 8 bit systems. Maybe a C64.
A good starting point for most assets is KenneyNL: https://kenney.nl/assets
...but I'm not sure he has 8-bit tracks.
This sounds right and only has an attribution requirement: https://ericskiff.com/music/
