That's the way to go if you want to play old arcade games (ah, the memories) on your PC.
Just dld the thing and dld a ROM and you're good to go (or, rather, your B/F is).
If he really likes old games like that, I think he'll have enough to satisfy his hunger for quite some time.
PS: I edited out the name of the game out of precaution. I think it's still copyrighted.
