Man I found some real treasures...
A original packaged interactive story, Detective Conan (Case Closed) game for the Nintendo Wii, and rare memory cards with adapter for the Nintendo Gameboy Advanced with original episodes of Detective Conan sold in Japan. Love that kind of memories coming back to life.
So I have to go through around 160 old games in the coming weeks. Yay!
Found my PS One, N 64, Gamecube and a lot of games. Also a PS2 / PS3 and tons of stuff and accessories.
I need a bigger house :)
Edit: I almost forgot, I found a Atari VCS2600, too. It's not the original one I once had, but a replacement with the "new" shape.
