Games by Unknown Manufacturer
Star Trek
Real mystery! One some unit of a bootleg on Head-On made by Sidam
and emulated in MAME ("headons"), a ROMswap has been performed, and
the original game has been replaced with this cheap game.
You can emulate it in MAME 0.158 or later.
According to MAME database, this game is a work by Sidam. On the
PCB, the dumpers have found a label with the Sidam logo and the
writing "EdOn (!) modificato spaziale", which means "Head On
modified space-themed". However, Sidam used to place its name on the
screen, and there's no company names here; it's very strange, since
this should be its only "legal" game. Also, there's a unused string
("PROTON") contained in the ROMs.
Very thanks to Patryck and Piero Andreini
