QuoteWell...there are definately only 21 bits there. However there is some kind of hardware dithering going on. If you connect a single bit up to a monitor you'll notice that some of pixels that are on the edges of some picture flicker a lot. I'll admit it confused me for a while...I thought there was something wrong with my flip-flop latches. Once all the bits of a colour are connected through the DAC flickering edges dissapear. If anyone's interested you can do a simple test to see what I mean: Connect a 1k resistor to one of the data bits (the high order bits show it more clearly...the low order bits are a total pixel flickerfest) and another 1k resistor to the compostite sync output on the DAC. Connect other ends of the resistors together and connect that signal to the composite video of a TV.Maybe Nintendo thought this kind of dithering effect was so shit hot that the upgraded their specs.
QuoteHere's an interesting question: Can you use the DAC inside the GameCube Component Video Cable in place of what you have there? Or do the digital signals not match up?
QuoteYou certainly don't need a resistor, I've never used one in all my VGA/RGB cable mods. It is only there for a little extra security against frying stuff - but that's a pretty dubious as well.
Quotequality is great, there seems to be a little less noise when compared to the old NTSC mod.
QuoteOn a not-so-related note, does anyone know how the region lockout chip works? I had region modded the console before and as I was working with the RGB mod one of the wires from the chip came off. I tried it just for fun and all the games booted to the title screen but froze in-game...
