Well... I played this game when I was a little child, and it was from my cousin. Only thing I remember clearly is that it was a horizontal shooter for either the snes or super famicom (don't remember if it was released only in japan or internationally) and instead of playing as a regular spaceship, you play as a sort of gundam/robot instead.
I'd really appreciate if someone helped me remembering the name, since I'd like to play it again...
(And no, it's not Macross: Scrambled Valkyrie nor SD Gundam 2)
