Few months after posting just checked up and yes it was the Sega master system sorry about that,

Also In order for it to work there was a series of lefts rights and button presses though it escapes me now,

All done mind you With no Game In the Cartridge!

Wierd? True Yes

I remember thinking as a child my sega was possessed or broken when I could play this game with no game cartridge ,And coming back to it like 4 or more years later and being able to get to like 99th lvl it kept going and going .

Was a maze Game where you would take a snail through well a maze .

Frickin fun weird senseless game
