Chip number 132 is Snake, and can be obtained from Higsby in the form of Snake R after completing his jobs.
you can't. Dark aura can only be gotten in megaman battle network 3 BLUE. You get it by doing all the time trials in secret net. In WHITE, you get the Serenade chip.
Cheat, or enter a commlink with a friend who has the chip in their library. You should then be able to order it from Higsby with the OrderSys assuming your "complete the library" function is on.
no you can only link megaman games together if it is the same number like megaman battle network 3 blue to megaman battle network 3 white
Life Aura can be found on the Scuttle viruses in the Secret Area (repels attacks < 200 dmg), and Dark Aura is not available in White. I believe Dream Aura is a combo, not a chip (Dark Aura + Sanctuary, maybe?).
Good question. This is one of three instances for a standard chip where the busting level affects the type of chip you receive on top of its code. Fishy 2s will give Burner chips usually, but, if S ranked, (Custom style and standard chips may be a necessity) they will give up a Burning chip instead. Use oilbody to find them and Collect to ensure that you get their chip. S ranking a Mettaur 3 in Custom style with standard chips will get a Bigwave chip instead of a Dynawave chip. S ranking one of the Volcano family viruses in Custom style with standard chips yields a Volcano chip instead of a LavaCan chip.
Go to GameFAQs; they have a chip list FAQ.
Talk to Tora (either in the DNN building or at Wily's Base) to fight KingMan Alpha. Delete KingMan Alpha to get the KingMan v2 chip.
There is a Sanctuary chip located deep in the Secret Area. Other than that, you'll need to abuse chip traders and BugFrag traders, or just trade it from a friend. Or, cheat.

By deleting Bashers, which are at the WWW Base, or use the chip trader to get Magnum 1 A.
