Wii NTSC to Arcade RGB?
« on: May 30, 2018, 10:13:30 pm »
Hi, my end goal is to connect an NTSC Wii to a CGA 15khz arcade monitor such as a K7000.

What would be the best way to go about this?

Perhaps useful information:
I currently connect my Wii to a component CRT monitor and the picture is great. I want to get a similar result but with a rounded style tube. Most all CRT TVs that I have found are flat screen CRTs, and because I have dozens of arcade CRTs that do have rounded tubes, I would like to use one of these. I do lots of arcade tube swaps and so I wish to put an arcade chassis into a nice woodgrain TV running a hacked Wii for a gaming system.

There is a Mayflash VGA adapter I'd thought to use with a JPAC or a simple VGA to CGA pin adapter, but that looks to only do 480p. Perhaps there is another adapter to recommend. Perhaps I could get a Wii SCART cable and mod the settings so my NTSC system would output PAL60 for RGB and then get a Sync Strike SCART to RGB adapter (http://arcadeforge.net/Scaler-and-Strike-Devices/Sync-Strike::15.html?language=en), but I'm thinking there should be an easier/more direct way.

Suggestions appreciated, thanks

Test the resistance and see if you can just tube swap to a component chassis. That wont give you 15Hz but it will give you the "rounded" tube you're looking for.  I prefer to avoid converters when I can.

I don't know about physically modding the Wii, but using a softmodded Wii i was never able to force video modes. Any NTSC game i took and tried to force to output RGB would just crash the system, in either Nintendon't or discloaders (can't remember the name). I had no idea what i was doing though, so it might work if done right?

Right now I'm looking at getting an Ultimarc Wii AV to Arcade Monitor/Speaker Adaptor (Screw Connect) http://www.ultimarc.com/wii.html  This has terminal screws to connect to an arcade monitor RGB inputs.

I realize this ONLY supports RGB output for PAL Wiis, but I am thinking with homebrew emulators I can set it to PAL60 and then it will enable the RGB out and colors will work correctly. My sole purpose for this Wii console will be to run NES, SNES, Genesis and SMS games.

Does anyone have thoughts on using this adapter cable with the PAL60 setting in the emulators?

When the Wii outputs RGB it still outputs Composite video at the same time, but stops outputting S-Video. Either way there's room in there to test things. Get a cheapo Wii component cable off ebay if you need to. Boot with a regular AV cable, then force PAL60 on something. If the Wii doesn't crash, plug in your component cable while it's running and swap the Y cable (green RCA plug of component video) for the regular composite video cable (yellow RCA plug) in your TV. If the picture then shows up in black and white, you have not successfully forced PAL60 and RGB.

EDIT2: changed the above to make proper sense. If you boot any Wii with the component cable plugged in, it outputs component. But I’m not sure if it still outputs composite at the same time. Either way the above method will work to test things, because the S-Video/RGB switch is easy to catch.

EDIT: This is all obviously to test if you can get RGB before spending real money on Ultimarc hardware. That link you posted doesn't show the right connections. You'll want one of the cables, i guess, but i doubt that monitor will take an HD15 plug (VGA), and either way you'll probably want a video amp like the j-pac as well.
