YouTuber James Lambert is all about getting seemingly impossible tech running on native Nintendo 64 hardware, from cel-shading to complex shadows. His latest project is recreating Valve's seminal mind-bender Portal on the 1990s console. As depicted in a new video we get to see the 'portal' effect in action, and it's impressive stuff.

Mainly because we're talking about the N64.



It's a fascinating clip because he goes through his experimentation, with the big question being whether or not the Nintendo 64 could handle portal rendering. We get to see two layers of portals (that is rendered environments you can see through each portal), a conservative figure that he pushes all the way up to six and then finally, 14 layers. Again, running natively on N64 hardware.

James notes that the next step is to add sound effects and animation for the firing and rendering of Portals. He also provides a link to his progress, with source code, for those interested in running this very cool Portal experiment.
