Technically https://www.myabandonware.com/ should be legal, most games there you can’t get anywhere else so even if you wanted to give money to the people who made them you couldn’t. E.g. I found that website trying to buy The Sims 1, I used to have the cds a long time ago, but I thought it would be easier to just buy it again from GoG or something, but it’s not available to buy anywhere so it’s a hard for a company to claim you’re harming their sells if they’re not selling the product.
