lots of questions about fc twin, PLEASE READ!!!!!!

Post by bipolar kid 3000 »

mostly I need to know about the av circetry
what I am using for the main parts is the following:

1. psone screen
2. fc twin
3. standard snes controller



what I know but could be wrong:

1. the psone screen can accept rgb and composite video, and has left and right audio input.

2. the fc twin's snes section is able to produce an rgb sinal with nothing else needed however the audio needs an amp consisting of four 33k ohm resistors and four 104 ceramic capacitors



thing I am unsure of how they work or need clarification:

1. what is c sync for and where do I hook it up on the psone screen and the fc twin's snes portion?

2.how does rgb work :oops:


I'm to grogy to think any more Ill add more in the morning

please feel free to post if you have any thing to say
I swalow my gum because I'm to lazy to walk over to the trash can to throw it out

1. Yes
2. I have no idea, but you should be right if it's really a hardware replica

1. The C-Sync, or Composite-Sync is pretty straight forward. It Synchronizes. It basicially tells the screen about how to interpret the RGB signal, to put out a proper picture. Try connecting RGB without Composite Sync, you will SEE what it does.

Also, if you use a PAL SNES, the Composite sync is in the composite video, and the pin which should output it has 12V

2. Basicially it sends the amount of Red in each pixel (well it's not THAT easy, as it's analog, but basicially), green, and blue. And then it combines them. Meaning if you skip one color, you won't see that color on the screen, even tho the screen will work just fine (just without the color). All three combined on the maximum lightness produce white.

Check the wikipedia to it
