There are 3 mini-games that can be unlocked by playing quests online. Once you have them, you can download them in a special quest, ''Pioneer Warehouse'' which is also available online only. The difficulty does not matter and you only need to unlock each game once per character.
Just like in the Dreamcast version of this game, if you go into the menu screen (select the ''z'' button), you will not pause at all when walking by traps. This allows you to walk through trapped halls without stopping, waiting, or shooting the traps.
Players that successfully complete all challenge mode levels with a high enough rank can unlock special items. Note that the unlockable rewards are different for offline and online modes, with online mode having different prizes for Episode I and Episode II challenge modes.
If you have 10,000 Meseta on your character when you quit a game, you can access the Dressing Room feature.
To do so, just enter Offline/Online Mode. Get a hold of 10,000 Meseta and make your character hold them, so you can't have it in the Deposit Box. Exit the game by quiting.
Now when you go to select your character where you would normally get the options ''Comfirm, Recreate, or Cancel'' you should now see ''Dressing Room.''
Remember this costs 10,000 Meseta, and if you select Dressing Room and ''OK'' you will be deducted those Meseta. The features in the Dressing Room are limited only to changing Hair Style, Hair Color, and Clothing. Not something big, but after playing a certain number of hours with the same clothing, you can add change.
Do the quest ''The Fake in Yellow'' and find the doctor. After you talk to the person that gives you the quest DO NOT collect the mesta. Go back the red teleporter that is wavy and go back to Forest 1. Once you get there you will see 3 Rag Rappies that you can talk to. Go the the background with the waterfall and stand there. After a while a Chao will appear and will give you the ability to download games for your GBA in Pioneer 2. It looks like a GBA on a pole. You will also get the Tails Chao on your GBA.
