Title: SNES2 RGB mod
Post by: Sumez on December 16, 2004, 11:00:09 PM
Alright, I'm really confused by the page for the SNES2 RGB mod...

Looking just on the schematics, it seems simple enough:

But on this picture, it looks all different:

According to that, the blue wire and the 5V wire go to one leg of the capacitor, and the ground wire goes to the other, while the leg with the blue wire and 5V is also connected to the monitor output. That doesn't make any sense to me.

EDIT: I've looked a bit on the drawing and the schematics, and with some help from a friend, it's finally starting to make sense to me.
You should really get a new schematic, which properly shows how the capacitor is connected. :)

The diagram's a mess, I know.  Very, very old page.  Seven years is my guess.  Sorry about that.

Well how about this?  :ph34r:
Not sure if the capacitor is depicted correctly.

I don't use an amplifier at all when adding RGB to a SNES Jr - just solder the R,G and B wires (pins 20, 22 and 24 of the U4 chip) to pins 1,2 and 4 on the AV connector via a 100 Ohm resistor (I found that the signal was actually *too* bright without a resistor, a 100 Ohm resistor seems to be perfect).

The capacitors are just there to remove some interference.
You don't need them, the mod page says so, too.

If you decide to add them, please enlighten me on the more exact difference. :)

I have this SNES2 unit, and I plan to use it with XAV2 (RGB to S-Video) and XRGB2+ units. I don't have any TVs with RGB input, since I'm a proud North American, not some decadent european social activist :)

Do I need preamp, or I can get away with just soldering thick copper wires?

True dat sister! I think S-Video does just fine for 2d graphics at 320 x 224 pixels. Theres no way I'm trading my big screen TV for a hacked up Apple Or Atari monitor. Those consoles thats have some sort of VGA support may be of interest too me if I could afford a huge monitor.
