Spectrum Ports / Homebrew · SAM Coupé

Subaquatic

Independent check passed: cold boot from the final disk and 123 states and screens exactly match the source across a 120-update keyboard route. Gameplay runs about 16.5% slower on the tested route: 6.324 s on the 6 MHz SAM model versus 5.282 s on the 3.5469 MHz 128K source. Music callback cadence stays near 50 Hz, with no missed-frame gap observed during that segment. Original music, effects and images are retained; SAA rendering is approximate. 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.
