In the long time span since this article's last edit, multiple games have been released that officially run the PSP at 333MHz.
The first link for linux on the PSP appears to be down, downforeveryoneorjustme confirmed it, but I decided against removing it in case it was only temporary downtime, though the site's main hosting page seemed to be running properly. In addition, I updated the second link to go to the new page for that project.
In the external links, I removed the link to lik-sang because their site has been taken offline after they went out of business.
