Pick two :P.

This is a quick&dirty one that works for me:
Code:
Init:    move.l    #<seed>,d7    ; large prime numbers
    move.l    #$6be7d35b,d6    ; are good...

Rng:    swap    d7
    add.l    d6,d7
    eor.l    d6,d7
It's based on this: https://en.wikipedia.org/wiki/Xorshift
Looks like snake oil to me. Is there anything documented about the properties of this generator.
