I've wanted to take apart my SNES and its games ever since I bought it, and I
finally got the chance to. I've compiled a list of chips and labels found inside
the main console and a few selected games, and I don't know if it benefits anybody,
but in case it does...

You need a special screwdriver bit to turn the security screws. Although they are
impossible to find in electronics stores (I've tried), they are easy to find and
order online. The cartridges use a slightly smaller bit than the console.

Notations:
Each named chip or component will be followed by several lines of text found on it.
Line breaks and letter case are preserved. There may be typing errors and are very
likely some mixups between zeroes and o's, since they are difficult to distinguish.
Any symbols that can not be represented in text form have been substituted with either
their manufacturer name or a description of the unrecognized symbol between <...>.

Abbreviations:
SHVC - do not know, but you see it a LOT
CPU - central processing unit
PPU - picture processing unit
DSP - digital signal processor
ROM - read only memory
WRAM - writable random access memory
SRAM - static random access memory (in cartridges)
IC - integrated circuit (they usually use 'U' instead)
