As the title says, I'm almost at the end of Handmade penguin and was wondering if there are any resources for the last few episodes of the hardware specific code in handmade hero (episode 20-25). Thank you!

I don't know about the specific, but there are articles in the wiki that might help you.

- Tutorial/A tour through Xlib and related technologies
- Cross platform opening dynamic library and loading functions from it

Thank you so much, I think I'll have to read the SDL documentation for myself and figure things out on my own then...
