Sorry I forgot to finish my cheat for unlimited credits

After you get your weapons&power-ups of choice, immideately TURN OFF the WLAN SWITCH and a screen will come up saying that you were disconnected.
After that you should have the weapons&power-ups you chose.

P.S.:you can only change your weapons if you go back to the ad hoc or
Infrastucture(online),have the WLAN switch on, and then turn it off or it will make you use the limit of 100 credits.

Hope I helped

First go to the ad hoc on the multiplayer(MAKE SURE the WLAN switch is ON!)
Then,create a game(you don't have to have another person playing)
After that,go to the weapons&stuff
Choose the weapons you want(remeber ULIMITED credits not just 100)
My weapons of choice are:
Bowcaster,chaingun,or incenirater,
Guided rocket or orbital strike,
Wrist rocket,
Jet pack or stealth suit,
Stealth or regenerate health,
Healthx3
Speedx3
And capture ratex3(great for online battle)

Hope I helped,

First you go online (I use infrastrucure) then once you enter a battle change your equipment. Pick absolutly any combo you want (don't worry about credits). Once you made your combo, instead of going back or canceling, you turn your WLAN switch off (does not harm your PSP). Once it says disconnected and your going back to the menu go to instant action (or even go back online). You should have the combo that you had that costed over 100 credits.
I use this to get lvl 3 speed, health, and capture rate.

Adding on to my other cheat go to where you first went to change the time and just set it back by setting it back yourself or by the internet

If you don't want to wait for the 25th of December or the 4th of July to get those medals just go to Settings on your PSP go down to Date & Time Settings go into date and time press set manually and change the date to either 12/25/2007 or 7/4/2007 It has to be the year before the time you read this cheat or it will not work. Then just log onto multiplayer, create your own game, then go to game options and set the tickets to 25 and try to go to the smallest planet and try to kill as many people as you can and when it's over if done correctly it will say at the bottom "Endor Day Hero Medal Earned" or Something like that. Hope I helped.
