Strawberry v1.4.0

v1.4.0 — 2026-10-02

• --slot N (1–8) starts the ROM from that save-state slot before the first frame is shown,
  for launchers (Fruit Basket couch mode's Load button). --slot needs a ROM; an empty or
  unreadable slot prints one line to stderr and the game plays on from a fresh boot. The slot
  files are unchanged.
• Developer tooling: tools/mgba-ref.exe (built by scripts/build-mgba.ps1) captures mGBA's
  pictures, memory, registers, IO changes and instruction traces headless, and
  scripts/compare-trace.py diffs instruction timing against ours. gba-test gained --png-at,
  --regs, --poll, --trace-frames and --trace-cycles.
• Checked against mGBA: the Initial D garage's blank phone and technique screens and the "0"
  under the NES Zelda file name are pixel-identical (game content, not bugs). The music start
  offsets of the audio comparison come from mGBA's own timing: it scores 1768/2020 on the
  hardware-recorded timing tests that Strawberry passes in full.
• scripts/build-mgba.ps1: quote the CMake policy argument (PowerShell split it at the dot).
