SNES 1-Chip Brightness

Post by strygo »

After listening to Bob's critique of the MLiG SNES video, I have a question: similar to what is being discussed for handling the slight brightness of the SSDS3 (and the PC Engine in general) - rather than installing resistors on the board, is adding them to the cable a viable option?

It wouldn't be an ideal fix but it would work, yes.
I don't know what a good value would be, but it might be around 39 to 75 Ohm in series.

If you only want to fix the brightness for a few consoles, it would be better to do the mod internally, before the video amplifier.
But if you want a cable that works better with every 1Chip you come across, I can see how this could be useful.

Not a good idea in my point of view, too.

Wrong; calculated based on Upp = 1.6V coming out of the encoder / video amp:
- 18ohm NTSC
- 9ohm PAL (in series prior to the additional grounding resistor in SCART plug)

(Just curious) Why not? On the surface, this seems much simpler than cracking open the console for the average person. I'm not being argumentative - just genuinely curious.

Thanks,
