The SNES has several decoupling capacitors connected to (mostly) VCC and ground. On the jwdonald schematic, some of the are:

0.1 microfarad:

  • C85, in parallel with the F411 CIC
  • C90, in parallel with the S-CPU
  • C91, in parallel with S-PPU1
  • C92, in parallel with S-PPU2
  • C93, in parallel with the upper VRAM chip
  • C94, in parallel with the lower VRAM chip
  • C95, in parallel with S-WRAM
  • C87, in parallel with S-SMP
  • C98 and C99, in parallel with S-DSP
  • C100, in parallel with the lower ARAM chip
  • C101, in parallel with the upper ARAM chip

1 microfarad:

  • C84, in parallel with the video encoder

This 0.1 microfarad decoupling cap is connected to VS:

  • C80, in parallel with the pre-amplifier op-amp for the right stereo channel
