Hey Austin the settings panel does work. Try using the more recent development builds of project 64.
Thanks for the tip; looks like it was fixed by Hack to get settings window working in wine (commit: 943f2d109b631bd3098cf2bc0be947fa89b74499)
which was first in v2.4.0-764-gd781003 on https://www.pj64-emu.com/nightly-builds.
This is still a bug, however.
