Galaga holds a special place for me because everytime my dad stopped by a machine, he'd wreak the high score on it and I'd watch in awe. I can't play it on my phone so I want it on my laptop.

Finding ROM's is like pirating games again, why are there so many sites that look like they're from 1990's? Thanks for any help /v/, my eyes are bleeding trying to search these shitty forums.
