  The core opens no file. src/ has no fopen, filestream or opendir call and
  libretro.c never asks for RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY; its
  environment calls cover options, logging, controller info, input
  descriptors, messages, pixel format and AV info. The Supercharger BIOS is
  a 294-byte routine compiled in (src/cart.c:195-235) and written into the
  ROM bank of every AR tape image (src/cart.c:300-319), the default
  tape-load header is a compiled table (src/cart.c:237-272), and the NTSC,
  PAL and SECAM palettes in their standard and z26 variants are const tables
  (src/palette.c). Content arrives in memory (src/libretro.c:596).

  Tia is an Atari 2600 core written for libretro by Eric Warmenhoven, with
  no standalone build; the repository is its own upstream. The version
  string is the commit count and short hash the Makefile bakes in
  (Makefile:36-37, src/libretro.c:595). The .info shows 26.
