Just found this game on the internet Project ZX which is a fun shooter based on the Sinclair Spectrum. It is free and worth a blas.

Been playing it for a few minutes and has some great 128 AY tunes and the graphics are based on classic spectrum games (think your ship is from zynaps)

Z-Exemplar is another nice Spectrum style shooter:
