He estado hablando con algunos frikis viciados y con dumpers de la genesis y por lo que me han dicho es pirata. Además, como ya han comentado antes, sería rarísimo que 3 juegos de Sega se pongan con 1 de Absolute. Imagino que habrán modificado uno de los juegos para ponerle el menú, creando el 4 en 1.
Sorry to say this to you, but it's not a pirate cartridge(pcb). It's something very unique from my country's once glorious days.
At one point in the late 90's ("A Company") produced some stuff under license from SEGA. The range of things produced go from consoles to even games (these all multi-region, so not region locked). The most regular MD game known from them it's the Sonic Compilation that even has a different artwork. And so the Purple SMS games and so on.....
(more details soon)
