Well,I belive that the problem in OOT of link being white is because of your videocard(not sure though),PJ is known to run well on GeForce cards an Radeons.
Also,PJ isn't optimized for P4,maybe that's why ZeldaMM is sometimes slow,but just to be sure,can you post your configuration?(I mean plugins and their settings)
