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...

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
