MOVES (Move and Set flags) is a Super FX instruction that moves the value of a general register into another general register.
According to fullsnes, the official documentation has the source and destination operands for MOVES mixed up. [2]
The flags are affected according to the datum moved. O/V will reflect bit 7, the sign flag will reflect bit 15, and the zero flag will be set iff the datum moved is zero.
The ALT0 state is restored.
Syntax
MOVES Rn, Rn'
Example
Let:
R7 = 4983h
After executing MOVES R10, R7:
R10 = 4983h
and the overflow flag is set.
