  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).
notes: |
  Tia is an Atari 2600 core written for libretro by Eric Warmenhoven, with
  no standalone build, so 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.
