A tribute to the 1997 classic GoldenEye 007 developed by Rare Ltd. for the Nintendo 64.
You must be referring to those RGB555 images in the ROM. They are oddly the only images using the RGB555 (and are unused). I've never tried to see what they'd look like though together, I guess just slightly higher res version of what's there heh, perhaps rendered from a scene with a bunch of jungle trees/ferns?(up to about halfway through second column are the beta ones)http://gyazo.com/c466e4ca050c131bba218000bcde6534
