This if how I did that in my cartridges and it works fine.

I was looking at this and I see your low pass filter (56pF cap, 1k resistor), and diode (low passing 1 edge, not the other).
I had added the M2+100nS delay circuit because I remember needing that delay when I wrote VHDL code for MMC1 a long time ago. But I don’t remember why now. Do you know if these 2 things are both accomplishing the same purpose? I will also look into this but I am just having trouble remembering what that was all about now.
