Title: TG 16 Turbo Express Region Mod Switched.
Post by: Drumjay on May 20, 2011, 04:40:39 AM
Thought I would post my Switched Mod for the TG16.
One thing I did find unusual is that everywhere I have seen this type of Mod it doesn't recommend grounding pin 29.
This goes for all TG 16 consoles. But on this particular model it needed grounding otherwise the TG16 games would not load!
So if you've got this problem before you de-solder all your wires and re-check 3 times! Just ground to be sure.
Anyway! Pictures.

Nice, I kind of always wondered where someone would fit one of those 8PDT switches inside an express and now I know.

Wouldn't your palm be right in the way of the switch?

Huh, yeah I never thought about that. Best to find another place for the switch if possible.

So you needed to ground pin 29 to make TG-16 games work but...I assume they worked before the mod, right?

I don't get that.

I'll try and shed some light to your questions.

The switch really isn't intrusive to your hand when playing games, as it only sticks out 5mm in PC Engine mode, and it's nearly flush in TG16 mode.

There is only one alternative for the switch, which is vertical, but it would mean removing the battery door tab and mount, it is possible, you then could remove the multi player port and fit it in there. I just found in this position it would be a lot more work, and you'd loose the port.

Pin 29 runs a check sum operation on game load, if you remove the pin in normal mode the TG16 games won't load, they don't work by default if you've removed the pin. This could be a different factor if your using a chip mod? All I know is that the instant it was grounded it worked perfectly :)
