Here it is: https://codeberg.org/hkzlab/Active_NESII_Adapter
Released my variant of the NESII adapter by @Btb

It adds an 4066 IC inside to make it handle some stubborn games that had issues with the purely passive adapter (at least on my Delta clone).

That's it. That's all there is to it.

Now I can play Maniac Mansion on the Delta. And boy that game is a pain on the Apple II.
