Avoid Random Battles (JP Version Only)

To avoid random battles, save your game about every 20 steps. This will reset the game's random seed, which also resets when your next random encounter will be. Now you can go through the entire 'Net without running into a single fight, or resetting your system because you got into a fight!

Easily defeat Dark users in Multiplayer

In multiplayer, Dark users are very tough because they become the Darksoul when you reduce them to 0 hp. However, if you use a chip or PA that freezes time and deals many hits, you can kill them without allowing them to become the Darksoul. A great example is the Pile Driver PA. Hope this helps you take out those cheap Darkies!

Secret Dungeon

There is a large hole surrounded by purple slime on a platform in Ura Internet area 6. In order to approach it, you need the chips ''Bug Charge'', ''Muramasa Blade'', ''Black Wing'', ''Element Dark'' and ''Poison Anubis''. Once you get close enough, it will suck you down to the secret dungeon, Black Earth.
