Quote from: panzeroceania on April 27, 2012, 04:20:10 amhow can you tell which decks have it and which don't? I'm happy with RGB (I live in the USA) but it is an interesting bit of history.
Quote from: ogre on April 29, 2012, 04:22:23 amHi new to the board with a question on this mod. Is there any other components needed to make this work off the chip properly? I soldered the 3 outputs and while it looks mostly correct though the picture is quite dim. It seems as dim as when you out leave off the coupling cap for RGB.
QuoteToo bad many HDTVs won't even lock on to a 240p component source though. But this would definitely be the best option instead of buying an inexpensive RGB to component converter. The Kramer FC-14 works perfectly... but is a pricy unit. Then again, I just use an XRGB-mini!
Quote from: airs on October 02, 2012, 05:27:21 amUpdate - my early model SNES works great using the method described by Ace on sega-16.You'll need two transistors (I used Fairchild C945) and two NPN transistors, 1kohm. These are used on the R-Y and B-Y signals from the BA6592F. The transistors are to be wired parallel to ground, preamplification. For Y, you can use pin 7 on the AV multi out, no transistors or resistors needed.I'll try to post pics soon.
