Someone made a modern game editor/SDK for the N64 and its insane. It makes the N64 look like a fucking PS2.

@enigmatico the issue with the N64 was never really a lack of power, it was a severe lack of space because flash storage was expensive as hell, and the fact the hardware was so bloody complicated it made the PS2 look simple

I heard the "trick" modern n64 homebrew devs use to get higher res texture is to abuse the feature of n64 so it can use two textures overlayed on an object at the cost of one by processing them in parralel somehow, and it was rarely used in official games and even only then for like one object in scene. Nobody knows for sure, but some assume the reason why is because documentation wasn't clear and devs didn't know it was practically zero-cost, since modern homebrew uses that all the time with no issues (though ROM size constraints were probably a factor too).
