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!
Once you beat the normal Navi decode this AJEKDUR2437561 and put it into the Staff Code window.
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!
The Save Icons are as follows:
After you get the chip NeoVari N from Undernet5, you can push the A button for a slash that does 240 DMG. But, if you put in certain combonations while you hold the A button down, you can increase the range of the sword.
When Higsby gets the NumberMan Trader, enter these codes to get the items.
To obtain the rare giga-level battle chips, you will have to complete some of the game's most arduous tasks. It is expected that you have an almost full-library and high stats before attempting to obtain most of these.
To get past the gate in Ura Internet area 5, you need all 150 regular chips. Once you get past it, you can fight the secret boss, Forte, and get his chip, Forte.
After completing the Black Earth dungeon, exit (plug out) and re-enter. You can now encounter Forte SP in Black Earth area 2, and obtain Black Barrier from him.
