Raycasting on an NES

Well, Famicom rather, but it does work on the NES too, haha. Here’s a textured raycaster running on my AV Famicom, but it should work with any other Famicom-compatible hardware. I already posted this on Twatter but I need to post this here as well because I want to send it to 3DSage in his Raycaster tuto comment section as I promised him I’d do that...
