S-Video on PSOne Screen. You can't do it..

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

If it has composite, there must be a chroma encoder somewhere on the board where there is rgb before encoded to composite.

Actually, you're wrong. you should learn more about video processing and encoding before you make broad statments and assumptions like that.

Not all graphics processors output RGB. For example, most DVD players nowadays output native component. Laserdisc players are another example- most only output a native digital Y/C signal which is encoded (like the Laseractive).

The encoder chips on N64's are not as simple as other systems and neither are their inputs (aka the processor outputs). It's not a simple RGB->NTSC encoder like the CXA1645 but a far more complex digital RGB processor that pulls several inputs from the main circuit and composes Y/C and composite outputs from that. Only early model N64s composed RGB from the digital inputs. and the circuit is Nintendo's own chip, which is the biggest problem of all.

Say it ain't so!! I was really looking forward to using these PSOne screens with my xbox. I guess I should find a way to output the xbox to RGB huh?
