Already played most of retro in the past

There are also amazing games like Legend of Etad which is also 12$ but on itch, but I've only seen free dumps on any site I searched for

Yeah, but I don't think that will my current budget buying a calculator for 5$ is not really feasible... That's not even talking about getting the console (200$ preorder or more on ebay (the only way), not even including shipping). There are games like P-Racing which costs 12$ and which are worth their buck, but there is also calculators and clocks...
