Piracy is bad, but if there is no legal alternative, then it's not a shame to upload all your favorite nes games here. For snes, sega, gba it is better to take snes mini - there are more buttons on the gamepad, and everything will not fit on one console. Those who say that itโs cheaper to take a Rasberry Pi and do the same - add the cost of hdmi, usb cables and a high-quality gamepad (for example, hori about 2), but here itโs cheaper, and you donโt need to do anything if you are content with complete games, which are enough for a long time.
