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.
White has no Punk, has Mistman (not Bowlman), and has the gigachips Navirecycle, Balance, Serenade, and Bass. Blue has Punk, Bowlman (not Mistman), and the gigachips Folderback, DeltaRayEdge, Darkaura, and Bass+. That's more or less it. The Punk chip is still only available by special event (long since over) and cheating regardless of version.
Well . . . Um . . . cheat. You MIGHT be able to trade . . . megachips? I don't think so . . . Cheat. Best bet. Actually, I think when entering the commlink, there's a possibility that the complete the library function may be on, in which case you might be able to order the chip from Higsby with the OrderSys. A friend with the blue version and a copy of the Bowlman chips is required.
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
455
Rank 2 is obtained from Bowlman in Blue and Mistman in White. Both are located in the battle terminal in the DNN studio. Just jack in, talk to them, battle them, defeat them, get rank 2.
you cant
No, it's not.
Oh boy. Search Megaman Battlenetwork 3 White ROM on Google and you'll get enough hits on the first page to download at least 3. But don't ask that question. Please.
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.
DNN's BattleComp. It's Mistman. Basically a mechanized Aladdin's lamp. Have fun fighting your virtual genie.
then you are done.... . . . Assuming you did EVERYTHING. But there's lots to do if all you did is defeat Alpha. Hint: go to HadesIsle, the Hospital Basement, and the Undernet server.
AntiDamage M is bought from the Sci-Lab Square net-shop in Blue. I'm not sure about White, but you can try checking Gamefaqs for an answer.
