Similar to the pirate Supervision cartridges also produced in Asia Spica have ripped off the basic design and color of the original asian cartridges. As well as Supervision Spica also used the same label art on most of "their" games, I guess to save money.

Spica put the words Original, Starwar and Top Gun on the label, like that would help sales.

For some reason Spica decided to take the title screen from Turtles 1 and put it on Turtles 2 then added a number two to the top of the screen. On Turtles 3 they have edited out Manhattan Project and added a 3, why did they bother?. To switch between the two games you have to reset the system as there is no select screen.
