Rebuilt twin famicom

*edit*

Video of gameplay from it.




Some pictures of how things look right now:







Original worklog:

This's a work in progress. I've been rebuilding my twin famicom using all the new tricks I learned since I last worked on this beast. There's a bunch of stuff I installed last time I worked on it such as the n64 multi av port on the side and the swapped expansion port with a standard connector.

Here's the top of the pcb with some wires left loose for audio stuff which isn't wired up yet:



Here's where the rgb / s-video / audio upgrade kit is installed:



Unfortunately distance between the ppu and the video encoder increases video jailbars. Therefore I needed to relocate the entire 40 pin ppu socket in order to get the video output completely jailbar free.

Here's the relocated ppu socket:



And last but not least, what it's all about:



Yeah it's a thing of beauty.

I'm going to work on the audio wiring using a new trick to remove the low pass filtering on the built in audio circuit thanks to ace. If audio is all good I plan on wiring the controller connectors into nes controller ports so I can use a regular dog bone controller on this thing.

Progress:











Currently there's two audio circuits selectable by a switch. Default audio circuit with the low pass filter removed and the f-labo circuit which I may tweak later. I wired nes controller ports into it too.

great. now all you need are some nixie tubes that say twin famicom.

or just build a quad 12ax7 amplifier for the audio.

A wonderful idea by skips:



I didn't wire up the special controller connections, I probably should have.
