Nintendo Famicom

Hello again…

I’ve been busy with work – a lot – but have found time to mod the old Nintendo Famicom to give a composite video output, for use on TVs with an AV input.

I’d read a *lot* of guides on how to go about doing this, with the writers having a range of successes, but a lot of modders kept getting ‘jail bars’. Jail bars are the vertical lines that run the full height of the screen at repeated intervals, that are caused by the clock/processor interfering with the video signal. My first mod had jail bars, but I thought they weren’t bad. The jail bars on my stock Twin Famicom were worse!

A few months later, after modding a second Famicom, I read some more, took bits of info from a few different blogs, and put it all together. The next FC looked glorious. No discernible jail bars at all. I immediately returned to the first unit and re-did a few parts, and that too looked fantastic.

So my intention is to write up a bit about how I did the mod, which may prove useful to others. In the meantime, here’s some more pics…
