"Portal 64 Developer Addresses Fan Backlash Over Valve Takedown"

The developer of the Portal N64 port, Portal 64, has revealed that Valve asked him to take down the playable build due to its reliance on Nintendo's proprietary libraries. The developer, James Lambert, explained that he expected this request from Valve, as the project was using Nintendo's LibUltra, and he urged fans not to be mad at Valve, as he understood their position. This incident highlights the challenges faced by fan projects involving copyrighted material, as seen with the recent takedown of Team Fortress: Source 2, while some community-made mods like Portal: Revolution have received official approval from Valve.
