NOAC - MMC5 fixed

[19rsn007]

So here is a little something I have cracked my brain on for the last couple of days, but did manage to get it working.



Here you can see my Nes-On-A-Chip running castlevania 3.
I did it earlier on a 60 pins (FOAC) version, but today I took a 72 pins version and got that working as well.

Now there is another main issue in NOAC's I am wrecking my brain on and that's the fact NOAC's don't have CIRAM (2k ram inside the PPU). I wanna see if I can manage to add that externally.

Here's a link on the 60 pin version I am working on (my Frankenclone project)

So what did you do to make it work?
Could you provide the video amp schematics also?
I have the same MD2 shaped noac in my junkpile - also has only RF output.

Ok so now I have it fitted in the case again and I was testing the thing.
I am still gonna try to see if I can manage to add the CIRAM externally.
If I can pull that off, my NOAC has PERFECT compatibility :-)
