This repo contains a few demos of this and that - all related to “web / javascript” somehow.
See the project here -> https://github.com/simonberinglarsen/simonberinglarsen.github.io/tree/master/ghostngoblins
This repo is a rewrite of the ghost’n’goblins music on the c64 into javascript - originally sid tune was created by Mark Cooksey in 6502 machinecode. Hopefully this will give you some insights and inspiration from the good old days - and knowledge about how “they” created that special chip-tune music back then!
