% codespell --ignore-words-list=gameboy,ist,mata,nd,openend,theses --quiet=3 --skip="./archive/*,*.html,*.js --write-changes"

Removing *.html from --skip would show approx 140 more typos.

Thanks! Skipping the HTML makes sense, no need to fix all the historical documentation.

It might be nice to add this to the Makefile either here or in a future PR. I think we would want something like

• add codespell to the virtualenv build command
• add a .PHONY codespell step and (optionally) change the build step to depend on that step and to fail if there are typos
• add an appropriate config file, and use --config in the codespell invocation (rather than the magical .codespellrc or setup.cfg so that future me will understand where the config values are

Note the Makefile uses a non-standard > prefix so I don't have to change my editor's tab/spaces replacement policy.
