Well, due to the success of my previous post, publish a new post with photos of PAL console model. I encourage you to encontreisi differences between the USA Motherboard and the European Motherboard.

typically the encoder settings and clock are the main difference.

Looks like the TCT-976 has been reconfigured for PAL output and the CXA1145 has been rewired to generate a PAL color subcarrier frequency. What about the NES and Genesis boards? What's different on those?

And I still see 3.3V RAM on this thing... but it looks like there are some voltage regulators... being shorted out by a 0ohm resistor! What's the friggin' point if you're going to short the damn regulator with a 0ohm resistor???

A friend of mine a forum in Spanish. has changed its PAL console with a switch and now can perfectly play all PAL and NTSC games on your console. I can do the same with my console NTSC?

That actually doesn't fully set the Super NES side to NTSC. What's actually being output from the console when the TCT-976 is set to NTSC is actually PAL60, which is essentially NTSC with a PAL color subcarrier. In Europe, this shouldn't be an issue, but in North America, some TVs will display the video signal with no color.

Now, can I get pictures of the NES and Genesis boards? I would like to see if anything's been changed on those boards.

I just asked the friend if you can spend the pictures, I am waiting for your response. But you tell me, Can I make a switch and make the motherboard work SNES 50hz me ?, If so tell me where I should lso soldering wires to the switch, thanks.

You have an NTSC Super Retro Trio? If you do and your TV can handle PAL video with an NTSC subcarrier, you can simply wire a switch exactly like your friend did. That will give you PAL and NTSC compatibility on your Super Retro Trio.

Now I found a video of the PAL Super Retro Trio and it seems as if the NES side runs like a Dendy, i.e. it has PAL speed and PAL video output, but its audio is like an NTSC NES. The Genesis side, though, appears to be stuck in NTSC or perhaps the region switch actually works properly for setting the TCT-6801 to PAL and NTSC. I would need to check the crystals used on each board. It should be 17.7314MHz for the Genesis side and 26.601712MHz for the NES side.

Hello. Yes my USA console is, so is the NTSC model. But I can not see where you connect the switch to the snes area. Could you tell me where ?, thanks. Is the PAL and NTSC mother board are different things are in different places and have some different components.

This is my snes NTSC motherboard

There's a small trace between two points on the N-P jumper pad that needs to be cut. Once that's done, if you want to permanently set the output of the TCT-976 to PAL, put a blob of solder on the pads like on your friend's PAL Super Retro Trio. The extra components are not entirely necessary if your TV handles PAL video with an NTSC subcarrier. The critical point is that N-P jumper pad. Do as I said to set the TCT-976 to PAL, then see if you get video in color. If you do, the video encoder doesn't need to have extra components added so it generates a PAL color subcarrier frequency.

Hello. You can forgive me ?, I have not understood anything, sorry. Say something of a NP bridge. Where is this bridge ?, I'm not very good with electronics. Do not want to permanently convert PAL console, and want to make a switch to change from 50 hz to 60 hz when I want. Please, I would be very grateful if you point out in the photo the exact area where I have to solder 3 wires to the switch. Thank you very much ;)

See the trace linking the N side of the N-P jumper?

It's indicated by a black arrow. You have to cut this trace, then solder a switch like the one your friend used in the exact same way he did. If it's too hard to see, you can click on the image to enlarge it.

hello
Thanks for the explanation. The friend of the plate PAL answers me, not even to say NO, in short, wanted to have happened photos MEGADRIVE area and NES that you wanted, but as nothing to me ...
IN SNES area carrying a glass plate that has NTSC, why?

Anyone know why the game Megadrive / Genesis Pier Solar And the great architeets not work on the console ?. If I put it on the console is turned on but it gives black image in both PAL and NTSC mode mode, however in my Megadrive 2 Modified normal running smoothly, why?
