Gakken LSI Game Invader 1000 Gakken Showa Retro Thank you very much for viewing this product from among many others. This is the Gakken Invader 1000. The box, styrofoam, main unit, and instruction manual are all included. Considering its age, both the outer box and the main unit are in relatively good condition. The operation has been confirmed with batteries installed. Sound, missile firing, and left/right movement have been confirmed. The left movement seems to be a bit sluggish. It seems to be designed so that it doesn't stay in place unless the stick is tilted in the direction you want to move. The battery case has some rust, but it worked without any problems in my home environment. This is a very old item stored at home, so we cannot accept any claims or returns. Thank you for your understanding. Rare, out of print, hard to find, video game, antique, vintage, original, game watch
