You're transforming the banding into dot crawl by using a crystal for color carrier frequency.

Would an S-Video mod eliminate the dot crawl?
The MegaDrive I'm using is a clone, it has jumpers to set many features, but unfortunately it hasn't an US/JP jumper.
I added a switch to do that, but looking at it today I see I totally goofed up back in the day

It was being used without a top cover, wich I only could get several months later.
This is the MegaDrive in question:

I think it's up to you to decide what is better, both options are fine, I think.
Anyway I really wish to see how this mod will be made.
So please, post as many pictures and videos as possible.

Having an original CPU/PPU set would certanly help in
this project I started a while ago but it is just stuck right now

But I'm worried about the costs, specially the shipping.
