RetroRecomp v1.6.1 — Super Street Fighter II converts again, one shared base, the previous release only

• Super Street Fighter II (Mega Drive) converts again. Its conversion was
  refused for many releases: a few sound writes came 18 cycles late from frame
  1,927 of the demo. The deferred sound CPU answered a bus request one step too
  late when the request ended a grouped catch-up; it now answers at once, still
  deferred, so no speed is lost. The game passes the native/reference comparison
  over 3,600 frames with 0 interpreted 68000 and Z80 opcodes; Sonic the
  Hedgehog and Gunstar Heroes give exactly the same final checks as before, and
  a ROM-free sweep of 32,768 cases guards the fix.
• One shared base. The base of paths travels in one line, CPU-keyed
  (format 3). Converters from 1.6.0 keep receiving it; a player far behind
  catches up from the newest complete base without reinstalling.
• The previous release only. Exports, F8/F9 quick states and bases of
  1.6.0 carry into 1.6.1: exports are rebuilt from their learned paths and
  rechecked, Mega Drive, Neo Geo and CPS-1 states load (Windows), and the
  Super Nintendo state key did not change. Support for releases before 1.6.0
  is removed: their exports are converted in full, their states are refused,
  and converters before 1.6.0 are asked to update instead of receiving the
  base or sending discoveries.
• Linux: an unpacked game is said in the window. When UPX cannot compress
  a large Linux game (upx/upx issue 18937), the conversion log now says so, and
  the Neo Geo validation file names the unpacked file that was validated.
