notes: |
  Sinclair emulator by Marat Fayzullin, covering ZX Spectrum 16kB, 48kB and
  128kB, Spectrum +2, +2A and +3, Timex TC2048 and TS2068, the Slovak Didaktik
  Gama, the Russian Pentagon and Scorpion clones, and the Sam Coupe. The build
  read here is the free Android package com.fms.speccy, versionName 5.9.11
  versionCode 5911, taken as the Play app bundle drop, xapk sha256
  a93f2fd474234291d2c0dee57885204ffb12a22c94602fdfcdfbf084ed7cb354, base apk

  d09469e9b550cbc9005d3bd089f3df5f0ba89cba71cdd3b33736a0382d6f9848, beside a
  Play distribution source stamp in the signing block. The paid package
  com.fms.speccy.deluxe, last published as 5.9.3 versionCode 5903 in December
  2021, is carried by no mirror that answers: the author's site links only to
  Play for it, apkcombo bounces its download page back to the app page, apkpure
  redirects to its generic downloader, apkvision holds no copy and archive.org
  none either. The native libraries keep their symbol tables, so the readings
  below cite libmain.so offsets in the x86_64 slice; the arm64-v8a slice carries
  the same nineteen ROM names. The free Speccy 5.9 builds for Windows and Ubuntu
  were read beside it and open the same names with the same lengths and the same
  order. No source has ever been published: every download on the site, from 1.7
  for MSDOS through 5.9, is a binary package, while ColEm and fMSX on the same
  site ship source archives.

  One directory holds everything. MainActivity hands the home directory to
  jniStart, which copies it into the buffer GetHomeDir returns and passes that
  same buffer to SetPrivateDir, and Application stores what GetHomeDir returns as
  the directory LoadBIOS changes into before it opens the first ROM and back out
  of when it is done. That directory is external storage
  joined with the application label up to its first space, so /sdcard/Speccy for
  the package read here, falling back to getExternalFilesDirs(null) when it is
  not a writable directory; the author's own instructions give the same
  placement. Every open goes through mopen, which calls OpenRealFile first: the
  name is tried as given, and again as <PrivateDir>/<basename>, keeping the
  larger of the two when both open. mopen then layers gzdopen over the
  descriptor, so any of these files also opens gzipped, and a content:// name is
  routed to the Android storage framework. The desktop builds have no home
  directory of their own and open every name where they stand, which -home
  changes for the system ROMs alone.

  LoadBIOS drives the whole set from one word of hardware flags, calling
  TryLoadROM once per name in a fixed order with the length to read and the bit
  that asks for it. TryLoadROM does nothing when the bit is clear, and clears
  the bit when mopen fails, which is the only check the emulator makes: the
  count mread returns is compared against the requested length solely to pick
  the word it logs, OK or FAILED, and a short read leaves the bit set. Nothing
  else about a file is examined and no hash is compared. A machine ROM that
  loads clears every other machine bit and a peripheral ROM that loads clears
  every other peripheral bit, so one machine and one disk interface stand at a
  time. StartZXS gives up when no machine bit survives, logging FAILED TO LOAD
  SYSTEM ROM! and returning zero without starting the emulation, which makes the
  ROM of the selected model the one file the emulator cannot run without.

  Two names are reached only through another. ZXS128TR.ROM is tried in place of
  ZXS128.ROM when the 128kB model and the TR-DOS interface are both asked for,
  and ZXS128.ROM is loaded after it when it fails. The Multiface bit picks its
  image from the machine already loaded, MFPLUS3.ROM behind a +2A or +3,
  MF128.ROM behind a 128kB or +2 and MF1.ROM behind a 16kB or 48kB, and the 8192
  bytes at offset 8192 of what it read are copied into the page below the machine
  ROM.

  Thirteen of the nineteen ROMs ship inside the Android package. MainActivity
  reads assets/memfs.mp3 whole and jniStart mounts it through SetMemoryFS as an
  in-memory filesystem, which mopen consults only after OpenRealFile has failed,
  so a copy in the home directory is served ahead of the packaged one. The
  directory is a run of 32 byte entries, a length then a name, closed by an entry
  with an empty name whose first word is the key: rotated left by three times the
  entry count, XORed sixteen bits at a time into each length and rotated right by
  three after each, it yields the thirteen lengths, which run consecutively from
  the end of the directory and account for the file exactly. Eleven of the
  thirteen are the same bytes the Windows and Ubuntu distributions ship, and
  TC2048.ROM and TS2068.ROM appear in no distribution at all.

  Companion files come from the loaded program's path. LoadFile derives .sta,
  .pok, .cht and .pal from it and reads each when it is there, and the startup
  palette is a name of its own, <HomeDir>/Speccy.pal on Android and Speccy.pal
  beside the binary on the desktop, which -palette redirects.

    note: "The package ships no cheat set. Cheatopedia looks for the file in the package assets, then in the home directory and its subdirectories, and takes it from Speccy-Cheats.zip in the Downloads directory when that is newer, unpacking it into <HomeDir>/Cheats. The author publishes that archive at fms.komkon.org/EmuAndroid/Speccy-Cheats.zip and states it is what re-enables the cheat features Google Play made him disable in March 2019; the copy read here holds this one file."

exclusion_note: >
  Left out are the files Speccy writes and reads back itself, which are emulator
  state rather than anything a user obtains: <game>.sta holding saved emulation
  state, which LoadFile restores ahead of everything else it derives from the
  program path, LOG.MID holding the MIDI soundtrack the recorder writes,
  <HomeDir>/PrinterOutput.txt holding what the ZX and Timex printers print, and
  the replay files of the instant replay recorder. Snapshots, tapes, disk images
  and screens are the user's own content: .z80, .sna, .szx, .scs, .tap, .tzx,
  .trd, .scl, .fdi, .dsk, .mgt, .sad and .scr all reach LoadFile, and the
  emulator writes most of them back. DEFAULT.Z80 is only the name the desktop builds
  fall back to when they are started with no file at all. names.dat is left out
  because the path is dead in this build: FileInfo opens assets/names.dat and
  <HomeDir>/names.dat inside one try block, and no split of the package carries
  that asset, so the failed asset read takes the home directory copy down with
  it. changelog.html is left out as the release history shown from the menu, read
  from the package assets and from nowhere else. The Android audio and graphics
  libraries the loader opens by name are provided by the system.
