People from Sirius was to be an arcade adventure game released by U.S. Gold back in 1987, after Mauro Spagnolo submitted a title to John Holder of Leader Distribuzioni.
The game would eventually see release via Your Sinclair magazine as a promotional release, as well as a release in Spain under the Topo Soft label.
It was suggested in Commodore Gazette (1987) that a C64 and Amstrad conversion would be following the early release on ZX Spectrum and MSX, but it was never to be.
After the game was released on Your Sinclair, the C64/CPC editions disappeared without a trace. At this stage, we are not certain what happened exactly, or even if the conversions were ever started.
Is it possible that Topo Soft worked on a conversion? Perhaps Jesús Miguel Medina was the developer? (who would code Mad Mix Game a year later).
Still plenty of research to go, but if you know anything more – please do get in touch! With thanks to Fabrizio Bartoloni and also Andrea Pachetti for his article on on Mauro’s Spectrum games.
