No.
you can't
There're no dark chip in MGM BTNW6
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.
Shadow Fire? No idea why you'd want that, but to get Shadow, use an Invis or Mole chip EVERY SINGLE BATTLE. As for Fire, just cross your fingers. It's ENTIRELY random. Using fire chips will NOT make you get a fire style.
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?).
Only in Blue, and a reward for successfully completing the Serenade Time Trials. These will be available after you defeat Serenade.
Shademan is a character from the Mega Man Battle Network series of video games. He is a dark and mysterious NetNavi who uses shadow-based attacks in battles. He is a powerful villain who serves as an antagonist in the games.
When megaman becomes worried (which happens after he gets hit a bunch of times without returning any damage) darkchips will appear in the custom window. Though you have to own them, obviously, for them to show up.

Kyloias : Chip is Light Gaia. He is released from the Earth along with Dark Gaia. Chip's purpose is to stop Dark Gaia to be fully released. Chip was released by Dr. Egg-man at the wrong time and caused Chip to lose his memory. AND I DID NOT COPY YOURS!
