The link you posted, vulpix, converts component to RGB.  The PC Engine already has RGB output.

There's a diagram right down the bottom

Sorry vulpix, I had accidentally hit 'next' and it opened the schem for RGB-YUV, I didn't even see the page to which you linked.

Good work.

QuoteI see that my modification interests you. Here's the basic info I used to modify my tg-16 for component video:

Once you have soldered the wires onto the huc6260 chip, you can either feed them directly into a homemade or commercial encoder internally and install rca jacks onto your system, or feed them to a port, in my case i used a 8 pin din, and them put them through an encoder such as a jrok:

Though the problem with the jrok and tg-16 is that the red is slightly overdriven, so the colors won't be 100% correct.

One other thing to note, you may want to use a lm1881n for the composite sync line, they are cheap enough and can alleviate problems with syncing sometimes:

Just got this from the guy who gave me the idea. I am going to have to outsource this one for sure thanks guys!! Now to tread the internet :lol:
