Set A and X to random numbers (though note that X is set to the random number that was returned in A the last time DORND was called). The C and V flags are also set randomly. This is a simplified version of the DORND routine in the main game code. It swaps the two calculations around and omits the ROL A instruction, but is otherwise very similar. See the DORND routine in the main game code for more details.
