The ZX Spectrum Next library continues to grow, this time breathing new life into a Sega classic. Developer dave18 has successfully ported the iconic Sega Master System (SMS) shooter called Astro Warrior over to the Next, a project born out of a nostalgic desire to test the architectural boundaries between the two machines. The developer chose Astro Warrior because it was the first game they ever owned for the SMS. While the port was created "just for fun," the result is a polished conversion that highlights the impressive technical overlap between the Sega and the modern(like) Sinclair hardware.
While the SMS and the Next share similar capabilities, the port wasn't without its challenges. The SMS features a larger tile data space, though it must share that space with sprites. By strategically rearranging data, the developer managed to bridge this gap. The biggest hurdle involved sprite priority. On the original SMS hardware, priority can be set on a tile-by-tile basis—a feature used in the Astro Warrior title screen to make lasers appear both above and below spacecraft. To keep the project manageable, the developer opted not to replicate this specific effect, noting that using the Next’s "Copper" or adding a second "Layer 2" playfield was more complex than the visual payoff warranted for a solo passion project.

Really nice port. Dave also said on itch that other Master System games could be ported also (some easier than others).
