Armored Core 2 Cheats

To save credits you must do the following. 1. After you have earned some
money from either a mission or an arena battle save the game. 2. Load
your game and do any mission you like. 3. If you fail your mission and
get less credits, go to the system and exit the game WITHOUT saving it!
4. When you go back to your game, you will have the amount of credits
you had before you failed the mission and also you would still have your
debt on the mission because the fail you did earlier wouldn't count. You
could save tons of credits this way. HAPPY SAVINGS !

NOTE: If your going to use this cheat only go straight to mission or
else you could lose what else you did before the mission. e.g. If you
buy a new part and then go to mission and fail then not save the game,
you'll lose the A.C part you bought. 

Successfully complete mission mode and allow the credits to complete to be able to have cores that are overweight.

While playing a game, press L2 + R2 + R3. If you entered the code correctly, a "Limiter Released" system error message will appear, and you will have infinite energy during this time. After approximately one minute, the "OB Down" system error will appear. It will last as long as the previous error, but you will not have any energy. After "OB Down" is completed, your AC will recharge and return to normal. Make sure you finish off your enemy before you become vulnerable.

Pause the game, then press Select
