On Megaman white 3 how do you get giga chips

There are a number of ways. NaviRecycle is obtainable from the BugFrag trader in Undernet 2 for 200 BugFrags, accessed through the gargoyle on HadesIsle. Serenade is received for beating the Time Trials, Bass is received for beating Bass GS, and all the V5 chips are obtained by beating their respective Navi, which won't happen until you have five stars. Balance can be obtained through random VS. battles. The Blue version exclusive giga chips won't be obtainable except through cheating since giga chips can't be traded.
