Augusto Ruiz decided to publish a Demo of his Street Fighter 2 port to the CPC dated from 2021. It´s the last demo he did when the project was still planed for disc release and Amstrad CPC 6128 as target machine. You can
download it here (https://www.mojontwins.com/cepeceros/descargas/street-fighter-2-demo-tecnica-por-augusto-ruiz-retroworks/)
Since then he decided to redo the engine and use the Roomba cart from Doragasu and target the Amstrad CPC 464, so what you find here is not what you will see when the port is completed. Enjoy!
It would be interesting to see how the game is currently.
