There's a nice video demonstration here: <a href="https://youtube.com/watch?v=V2kaV_m4iNU" rel="nofollow">https://youtube.com/watch?v=V2kaV_m4iNU</a><p>It would have been neat if Nintendo had set this up so the stock unit could have been expanded like this.
What I'd like to know is: Why did Nintendo allow the PPU to pass along another pixel color, but didn't take advantage of it in a shipping product?<p>Is this a case of "you ain't gonna need it" overengineering; or was the PPU used in other products. (And thus these pins were used elsewhere?)
The PPU (and variants of it) was used in quite a few arcade machines, in addition to the NES.<p>I don't know if there were any actual machines that used dual PPUs, but the functionality was likely intended for creating an arcade machine with dual-layer background graphics.
that's a really sweet ANES
great name following the NESticle lineage
Reminds me of a NES that I overclocked when I was around 14 years old. It was the sort of silly thing a nerdy kid would do with too much free time on their hands, and didn't do much to improve the system. Most of the time it caused more issues than it fixed, but it was a good learning experience.<p>This is far more exciting, since it adds functionality to they system. Maybe I'll dust off my old hacked up NES and do this at some point. If only I had the free time these days.<p>Thx for sharing :)
Oh man, A thing I literally needed right now haha
