Another port of Quake for the PSP has been released by Peter Mackay.
Thanks to psp-news for the news.
Release notes:
This is a port of id Software’s Quake to the PSP. There’s already an excellent port out there by PacManFan, but I wanted to code something for the PSP and it was a good project. I also wanted to port from the original id source, instead of the PocketQuake source.
