My favorite thing about the 10NES is how the easiest way to get a Famicom->NES adapter is to open one of the first wave of NES carts, because those were made on Famicom boards and then have an interposer with the 10NES chip on it. [1] Though in digging up a source for this, I discovered my new favorite thing, which is that Tengen (infamously) made a (mostly) cleanroom duplicate of the 10NES and got sued over it, and when a company recently wanted to make NES cartridges, they reverse engineered Tengen's chip in turn.
