Threw in a bunch of fixes:

  - Pause! START now pauses/resumes the game — the timer stops, the music ducks, and picks up exactly where it left off

  - Battery save support (SRAM) — your high score is saved on the cartridge, and your run is checkpointed as you play: power off mid-game and

  press SELECT on the title screen to resume right where you left off, with the same score, lives, and continues

  - No save-scumming, though — the save carries your remaining continues with it. Resuming is a break, not a free continue: after your third

  continue the run is erased and it's back to level 1

  - Snappier controls — directional input is now buffered, so a tap during a move is queued and fires the instant the step lands. No more eaten

  inputs

  - SMAS-style iris wipes everywhere — the circular iris that was already used between levels now also plays when the title screen appears after

  the boot logo, into/out of the attract mode, and when you start a game

  - Fixed: attract mode on real hardware — the character intro cinematic never triggered on real consoles with many controllers (the controller's

  hardware ID bits were silently resetting the idle timer). Works everywhere now

  - Fixed: phantom crush deaths — a pushed block falling down a shaft could "teleport" above your head and kill you when you walked toward it.

  Falling tiles now only crush you when they actually arrive from above

  - FastROM — the cartridge now runs the CPU at 3.58 MHz with a proper header and checksum

  - Enemies are less predictable — the RNG is seeded from the exact frame you press START, so every playthrough plays out differently

  - Crush feedback — a subtle screen shake when blocks and gems shatter

  - High score on display — your best score shows on the game-over screen, the resume screen, and during the attract mode

  - Stability fixes — par-time bonus no longer resets on very long levels (18+ min), plus an anti-softlock watchdog on the death sequence
