It was broken because the practicerom package changed stuff and apt didn't like whatever changed.
This is the commit that seems to have broken how the old practicerom package worked: https://github.com/glankk/n64/commit/e7bec93b0b11b37a63abcf5ac28728f2fcd4045b#diff-b335630551682c19a781afebcf4d07bf978fb1f8ac04c6bf87428ed5106870f5

Some references were broken in the markdown files, and there's no longer a need to run the git `safe.directory` command since the docker file was doing it already

* Update practicerom instructions
* Update practice rom again
