Here is something for you! I have Multi-X modded a Super Famicom with a switch for the cic and one for the PPUs. Works great and boots both PAL and NTSC games. Problem is when I switch to 50hz the picture goes black and white. Switch back to 60hz and color is back. I have tried adjusting the little screw (Is it a capacitor?) with the red 'hood' without luck. Need some guidance with this. I have modded several PAL SNES and all of them work flawless in both 50 and 60hz so I'm confident I have connected everything right. Since I live in Sweden I have PAL TVs, but they are all able to display NTSC signal over composite.
Solution: Use RGB. That's what you're supposed to do. Your TV is probably picking the 50hz vertical signal and automatically switching to PAL color decoding mode... Because the console keeps encoding in NTSC while working at 50hz, the color vanishes. Again, use RGB and the problem will disappear. :shrug:
Careful. Depending on the TV you may need an RGB scart wired for NTSC models. In Europe, Nintendo changed the pinout slightly from its original form. (PAL SNES released after the US and Japan)
A PAL Gamecube RGB SCART cable will work fine with the Super Famicom and US SNES consoles, but you will have to manually switch to the A/V input on the TV.
I'm thinking of buying this RGB cable from play-asia.com http://www.play-asia.com/paOS-13-71-24-49-en-70-64-4-6.html Should work.
So... I recieved my RGB Scart today and hooked up the SFC. Same shit, different cable. This is where I'm at. B&W picture in 50Hz mode.
That cable is wired up differently than the official SNES RGB cable. The good thing is that the AV connector in the SNES end of it got a full set of contact strips (as opposed to only the ones that are actually used), which make it easy to rewire it the way you want it and eliminate that possible source of error. I'd try rewiring the RGB cable according to this schematic before doing anything with the SNES. Replace lead part of the cable while you're at it, personally I find the image quality horrible with the original leads. Also, the solder joints are questionable at best, I've found several dry solders in those cables. Personally I've used VGA cables as donors when rewiring those cables, they got all leads you'll need, got individual shielding for each color channel and sync, are usually of high a quality, and most important, you probably already have a bunch of them collecting dust at home already Opening the scart connector is easy peasy. The SNES av connector is harder since it's glued together, but it's still not impossible to take it apart without destroying it by carefully cracking it open with a table knife or a screwdriver.
He made the common choice to add a hz switch, but not a color carrier switch. Most people don't install one.
By adding a color carrier switch I presume you mean installing a PAL clock in the machine and switch between that and the NTSC clock?
Yes, except that does not affect RGB mode. RGB is the native color format used inside the SNES graphics processor. No NTSC or PAL clock.
I'll try adding a PAL clock in the next SFC I mod It's not everyone that has a TV that has RGB scarts or are willing to pay extra for an RGB cable. Many thanks.
See systems like SNES, Megadrive, or Saturn, apply both 50/60 hz and NTSC/PAL in hardware. Bypassing region checks of import games on an unmodified console will inevitably force them into the system's factory setting. N64 and PS1 are different. They moved 50 or 60 hz to software. PS2 is even more different. Both 50 or 60 hz and color clock are in software.
So what can we do in non scart countries like Australia?? I have this problem also for a customers machine
You'd need to install a PAL color circuit. Not really worth doing for Super Famicom in most cases, but if you have one there isn't much choice. It's better to mod the PAL SNES which already does PAL color.
