genmddj v0.11

genmddj v0.11

A fixes release on top of v0.1 — same tracker, several real fixes,
two of which affect playback directly.

Download: genmddj-v0.11.bin (2 MB) — drop it on a flashcart or open it in any Mega Drive
emulator. The build stamp (V0.11 902B494) is on the boot splash and OPTIONS → VER.

Highlights

• Hung / ringing notes fixed — stopping the transport (Start or C+B) now cuts every ringing
  voice: FM key-off, all PSG voices to zero, and the wave DAC stopped. Held notes (esp.
  HLD=$F) or PSG voices could previously ring on after Stop.
• PROJECT master transpose now works — it was a dead field (editable + saved, but never
  applied); it now transposes the whole song.
• FM editor: the operator AM switch moved to the end of the operator row and is drawn as
  an on/off toggle box, like the LFO screens (was a digit mid-envelope).
• Splash trimmed to ~2.0 s PAL / ~1.7 s NTSC (Start still skips it).
• PERC (YM2612 CH3 special-mode percussion) confirmed on real hardware.

Companion tools — now round-trip carts ⇄ emulators

The browser suite in user-tools/ is fully in step with the save format:

• The save tool and bank editor now read and write gzipped emulator saves (Genesis
  Plus / Bannister battery RAM) as well as raw flashcart .srm, so a song moves both ways.
  Layout detection uses the GMD1 signature; config offset + VID/SYNC labels corrected.
• Wave editor .gmdj offsets and the de-re-interleaver readout were fixed.
