So I thought after we talked I'd revisit the Famicom jailbars and realised that with that upgrade installed, the cap across pins 20/22 of the PPU actually make NO difference at all.

When I was picking up video direct from pin 21 of the PPU it did make it look better, but when the PPU circuit is as normal (As it is for this upgrade) that particular jailbar fix is redundant.

As it goes the current jailbar situation is as I said, only really on big blocks of blue and is equivalent to the direct connect to the PPU via pin 21 with a comp mod WITH the cap, so it's really OK.

I will have a look though, see if there are any other options for improvement.

I'd still recommend the upgrade though :)

Here is a good video worth watching if you want to get rid of the jailbars:



It's in Japanese, but it's easy to understand what has to be done.

Thanks, I'll have a look 😁

EDIT - That's quite extensive work in terms of cap replacement and modding the PPU output. I'll have to have a think about that.

Of course, the other way to look at the jail bars is that they're part of the charm of a nearly 40 year old design. :-)

That's also a commendable point of view.

I don't entirely disagree with that PoV.

Well, while I try to decide if I let the jailbars go or fix them, I at least have the replacement rubbers coming through for controller 2, and they're in the country :)

That'll be up soon, and controller 2 is slightly different in that it has no start/select buttons, just the D-Pad and buttons A & B. However it does have a microphone, though not sure what software it works with.
