sadly there isn't a psvita version, and most likely won't be one
as i'm building a new engine and most old project will not be compatible with it
sadly it's not, as i wrote the engine in this game exclusively for the GameCube, and i would have to rewrite a lot of code to make it run on other platforms. which i will not have the time to do so,
but i'm open to giving the source code to you and you can take your time to port it to any platform of your choice if you'd like
