Hmm..

#8: Super Vulcan - You just beat the Last Virus Battler in Central Area 1. (Note: you must
have the Battler Card and have defeated the 4 Virus Battlers to make him appear.)

#141: Little Boiler 3 - You know where you can find Chargeman, right? The starting point
where Chargeman is the one you use (As a Linknavi, of course!). The Vending Machine
Computer is where you can find this virus. Battle it and get its chip as soon as possible.

#166: Grab Banish - This is not hard to find. This chip is in Mr. 2 Weather Computer Green
Mystery Data (Not in Battle)

#111: Meteors - This one's easy. This is in Graveyard. When you enter a virus battle with
a Green Mystery Data in it, make sure you get a S rank because sometimes it contains the
Meteors chip.

No need to thank me!
