Sgt. Helmet Zero

Sgt. Helmet Zero for SAM Coupé, Mode 1 and 512 KiB, from the original 128K edition with AY audio converted to SAA1099. Preserves six songs, nine effects and eleven images. Independent check passed: cold boot from the final disk and 60 keyboard gameplay states exactly match the source. Corrected handling of ultrasonic AY periods 0/1. Audio is approximate: AY level 3 rounds to silence in 382 tested voice updates; noise and waveform differ. No clipped samples in the examined native capture. Source/native speed comparison is unavailable; music cadence remains near 50 Hz during the SAM route. Joystick, physical hardware, other routes and game completion are unverified.

Requires a SAM Coupé with 512 KiB of RAM.

Emulator tests cover specific routes and components; this is not a complete-game or physical-hardware certification.
