I have tried to locate the exact cheat for unlocking all 30 missions in Star Trek Invasion for PS One, including hidden levels, and I have found at least three codes that do not work. Could you please give me the correct code for this? In addition, I have tried these cheats at the Stellar Cartography screen, and they do not work as well. Is it possible that maybe there is another screen in the game which this codes in designed to work on? Or, does one have to finish the first two missions before this cheat activates? Please provide me with these answers as soon as possible. Is there also a code which unlocks all the weapons as well? Thank you.
