A hi-res sprite compiler for Apple II
This was a project done for KansasFest 2017. The goal was to see what the maximum draw rate of a sprite on the Apple II might be, and play with the tradeoffs of size versus speed. This project includes a python script that takes a PNG file and generates Apple II assembly code to render that image anywhere onscreen. This is the essence of sprite compiling, and while it's common on many platforms, it never saw widespread uses on 8-bit Apple II machines. This presentation from KansasFest 2017 explains all the rationale: https://www.youtube.com/watch?v=byVvMsW__Cc
The python code itself is hopefully fairly self-documenting. There's not much to it, really. It just parses a PNG file, looks for colors that match Apple II hires colors, and generates code to render the images.
