theres an uprade for the navi custuomiser to use dark cips and still be normal i think or
if not use gundesol chips

do not know

in mmbn 5, there is a navi cust program called soulclen. If it is in mmbn 4 then it might
work. Soulclen is to clean a darkened soul. It makes you able to use sp chips again.

You need to use lots of recovery chips such as recover 30.I used a dark chip once,but I
revarted back to mega man.

don't use dark chips for a while
