Quote from: IJTF_Cinder on January 24, 2009, 10:39:21 amWhat's up with the SNES Jr. and the later models of N64 then? From what I've read from you guys and on the wiki, you can't get RGB out of them, but earlier models you can.
Quote from: IJTF_Cinder on January 24, 2009, 12:58:58 pmNo, I was under the impression getting RGB out of them was impossible.So you could tap RGB from the SNES Jr. right off the VDP?I don't even know why I ask about things I'll never bother with. Call me curious I suppose.
Quote from: Link83 on January 24, 2009, 03:05:36 pmYes, you can easily add RGB to a SNES 2/Jr see here for more info:-http://gamesx.com/wiki/doku.php?id=av:snes2rgb75ohm resistors in series seems to be the 'definitive' value, then just use a normal NTSC RGB cable (i.e. one with 220uF capacitors inside on R, G & B)

Oh and if your original SNES is one of the last models (You mentioned its a later model with no cart lock mech) do you know if it has one of the board revisions I mentioned above?
Quote from: Link83 on January 29, 2009, 06:20:18 am<SECOND EDIT> Just realised theres one other thing you could try - adding 22pf (or 47pf) capacitors to ground on each of the Red, Green and Blue lines after the 75ohm resistors - this should be relatively safe to try as Nintendo always seems to use these 'capacitors to ground' on all the video lines (R, G, B, Y, C & CVBS) for all their consoles. Lawrence even used them on the old SNES2 RGB mod and said these capacitors are "...just an interference filter, and you can probably leave it out entirely." but perhaps they are more important than I had first thought I'd probably try adding these 'capacitors to ground' first and see if they make a difference before trying the alternative Sync mod I mentioned.
