Megadrive/Genesis CD32x Switchless with Dual Frequency Oscillator

Hey everyone. It's been a while since I posted here.

I've update my switchless mod for my Sega tower of the death: Megadrive + Mega CD + Super 32X.


This time I used the DFO method, but I put the PIC16F630 on the bottom of a DIL Version.
I'm still using the D4S code.

I've also tried to put a proper Color Subcarrier for the 32x, but I have issue with the PAL one. :/
It is also supposed to handle the proper C-IN/C-OUT and Y-IN/Y-OUT

Next update will be a DFO for the 32x would be great, but unfortunately I don't have the skill. I found some equivalent of the CDCE913 but for a two pin oscillator, but I don't know for the programmer side. :/

 

Nice work! Saving this for when I finally finish my Neptune mod.

 

Thanks! I have to go with my family for new year's eve, but after that I'll update the depository. I need to explain the installation of the PCB in 32x.

 

What a tinkerer.

 

This is fantastic, I've been working on a similar project as well. I really like your work. Is it open source?

 

Micro release eveything since a while now.
My twist and the attempt on the dual subcarrier for the 32x are all available on github.
Here's all the links which are on the description on the video:
