PS2ME v1.2.0

Added

• Looping menu background music, played straight from the SPU2 as a hardware ADPCM
  voice (built offline by tools/mkbgm.sh), so it costs zero EE CPU and RAM.
• Opt-in in-game FPS counter (Settings toggle, default off), drawn outside the game
  canvas on the pillarbox bar.
• A "Menu music" toggle in Settings (default on) to enable or mute the background music,
  applied immediately and persisted to the memory card.

Changed

• The Settings list now scrolls: it shows the rows that fit and follows the selection,
  with up/down chevrons, so new options no longer overflow into the footer.

Removed

• Dead Milestone A scaffolding (src/, root Makefile, build.sh) that predated the
  phoneME MIDP pipeline. Remaining boot log strings were rebranded to PS2ME.
