If you own a Switch and took a test drive on the eShop, odds are you've seen the Neo Geo ports on there. Despite Nintendo's insistence to some developers that they're not accepting ports -- these games, among others, seem to be an exception.
It seems to be working out for port studio Hamster Corporation too, as they've just announced that they've sold 200,000 copies in total from their entire line on Switch (you can check out the full list here).
Note that it's across all regions and all 14 games, but it's still impressive nonetheless for decades old ports on a brand new system. I think just about everyone picked up one of the Metal Slug games.
