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)

Try to disable the "Change blending mode if invalide for video card" option,and see if something changes.
Also try to look for the latest drivers for your video card.

Maybe you could ask the help of Enigma1982,he too has a G400,and he (she? never knew ) doesn't seem to have this problem.
