I remember using those link cables.

Ahaha, they're hookedup.

Aw, I used to play Tetris like this with my friend when I was 12 years old. Nostalgia!

I remember doing this too, but it was using TI-86's instead of Gameboys.

Going by the Red and Green game carts, it seems likely that they're playing Pokemon.

You forgot the most important tag.

I still have one of those original gameboys. tat actually saved me a cartrage from being stolen right from in front of me once, because of the little tab that prevents the cartrage from being removed when the system is on
