Does anyone know where I can find schematics for this AV2VGA converter?

I'm thinking that, the video must be split into RGB by an integrated in order for VGA to recognize it... but I can't find where the Video (Yellow) connects.

Continuity test shows Video (Yellow) connects to a tiny capacitor (C21) but the signal doesn't go anywhere beyond that.

Tracing continuity from C21 to somewhere doesn't work neither. And trying to trace RED / GREEN / BLUE from VGA to the big integrated in the center connects to multiple pins at once.

I want to find exactly in which integrated Video (Yellow) splits in RGB but can't. I'm running out of ideas other than maybe it needs power but my Multimeter's probes are not that thin, and I'm risking shorting something.

EDIT: Just found that from C21, it directly connects to the IC's pin directly above it.
At the same time, said pin connects to C30, C47, C35.

I'm getting excited as I believe these are where the video gets split into RGB.

Now I hope I can find where those connects and if they're connect to VGA directly.

    The Touchscreen makes using system menu options for brightness and filter adjustments easier

    @ColdBlitz, who said anything about touchscreen?

    On screen keys would be cool if the rubber ever fails
  • Psionic Roshambo @ Psionic Roshambo:
    I feel like at that point might as well go emulation lol
  • Psionic Roshambo @ Psionic Roshambo:
    One of those RG things
  • K3Nv2 @ K3Nv2:
    Some people just like using original hardware for the hobby point of it
  • K3Nv2 @ K3Nv2:
    You can easily buy replacement buttons but it's a good fall back
  • ColdBlitz @ ColdBlitz:
    on screen keys would be cool but the gba screen is pretty tiny though :(
  • K3Nv2 @ K3Nv2:
    I'd rather use emulation but it's cool regardless again the main point of the Touchscreen isn't just for buttons but for menu options
  • ColdBlitz @ ColdBlitz:
    would be way better for menu options
  • ColdBlitz @ ColdBlitz:
    although I have huge doubts anyone would be able to make homebrew that would give support for the touch screen
  • ColdBlitz @ ColdBlitz:
    then again theres still people who develop games on systems as old as the nes for fun

    (
    micromages is amazing btw)

    I doubted 360 emulation would be possible

    yet here we are seeing ps4 and even some (very experimental
    ) ps5 emulation
  • K3Nv2 @ K3Nv2:
    Ps5 emulation? Why
  • Psionic Roshambo @ Psionic Roshambo:
    I always thought Saturn emulation would straight up be impossible
