Very nice collection you made, congratulations, just curious, always noticed that Casio has a lot of really good games and only a few are revived, is that for some special reason?
I would love to add more Casio games. The main constraint is finding enough material to be able to produce an accurate simulation of a game, like videos of the gameplay, scans of the packaging and, most importantly, scans of the original instructions. If you know of anyone who owns any of these games and would like to contribute they can get in touch through the community forum.
