Help please - region fix for TurboGrafx

[bacteria]

Hi - help please!

I have made an 8P2T switch and wired my US TubroGrafx in accordance to the diagram below - it plays US games fine, but refuses to work with my Japanese games.

What else do I need to do to make this work please?

As you see from below, I am at the last stage of the wiring for the system; I have already successfully rewired most of the game pins as I had to make the board smaller to fit into my case:

As you see, I am hardly a noobie!

So, help please - I have a few Japanese games I want to play on this!

Turned out I had some gunk in the switches which stopped some of them making proper contact. Sorted this out.

I got this to work, I can play US and Jap games now fine on the system.

HOLY CRAP. It looks like some kind of torture device for Hucards!
