There are a bunch of hacks / pictures floating around the web showing the incorrect way of adding composite video to a white PCE. The Core Grafx II adds some components to the output, not the least of which is decoupling capacitors. I added these to my white PCE and have a wonderfully working output.
Use in conjunction with the wonderful expansion port pinout available here: https://gamesx.com/misctech/pcebp.php (https://gamesx.com/misctech/pcebp.php).
Note, I didn't get the pinout of the preamp…it's a standard dual opamp and I was too lazy :O
Happy modding!

the fb koolaid has infected the interwebs.
Interesting, on the composite out it's much simpler than the Turbo Booster. Thanks for posting.

I was really curious to find more info on the guts of the turbo booster... Do you have a schematic for it? I would love to know the differences
