Just a fast very honourable mention of the large efforts that the MAME community undertook in order to preserve the original Game & Watch LCD handheld games from the 80ies.
As of MAME 0.223 every Game & Watch handheld is supported in MAME. While previous emulations, such as the Retroarch Core, were not based on the original dumped roms, I understand that MAME versions actually preserve the data of the old handhelds. Huge kudos for this, this was the time of sitting together and sharing the handheld from one friend to another. I particularly liked Mickey Mouse (screenshot below). This is very nice to look back.
However, if you only have the roms availabe, there is no way to play them properly. You also need the artwork.
