Funnily enough, I actually had problems in the past with junk roms in all-in-ones. I'm sure there are good, currated all-in-one images out there but I found the flexibility of managing my own library to be worth it cause there are so many great sources of roms. For retro, my favourite is vimms lair. Check it out if interested
This comment is very dumb and frankly quite rude. The company is defining the requirements for the application themselves - so they have no reason to reflect scientific uncertainty or whatever you're getting at in their ad.
Pretty reasonable. The title makes it seem like they have a hairbrained scheme...
