When you beat the game mutiple times, go back to battle data, you'll see question marks. The leading ones will be special items you can use in Advanced mode, you will only be able to use 2 of the items at a time, The more Battle Data you get the more Items you get, These will make Rockman more Faster and more powerful.
Select 2nd menu and Go.
If you have a "Pocket Station" you can make Rockman much stronger, you have to go in the mini game were you battle bosses, when you get your levels up, goto the Boss data screen in the game, Goto Rockman. You'll see a pocket station icon, when you select it, it'll ask you to upload (it wont hurt anything if you SAVED THE 00 level) upload it, the Rockman you leveled up will be shown and when you start the game Rockman might have a more HP and AT.
