So much for the super nes I still have just a study mode 7 and sound.
In mode 7, I know use but does not include calculations to do.
I can possibly copy source code but without understanding I could not use (or source code easy for me to make rotations).
I know that:
|X2 | = | A B | X1 - X0 | + | X0 |
|Y2 | = | C D | Y1 - Y0 | + | Y0 |
A = cos theta
B = sin theta
C = -sin theta
D = cos theta
I find it difficult, any help is welcome.
thank you.
