There is a glitch in the game that allows you to automatically earn the maximum amounts of ace points and skill points. This trick can be done at both the mech upgrade menu and the pilot upgrade menu. First, get enough points so at least one upgrade can be potentially purchased, but don't actually buy it yet. Then, make sure that the next upgrade (in either the same category or a different category) will raise the total cost beyond the currently available amount of points (if you press Right again, but don't do so yet until the next step). Next, press RIGHT and CIRCLE together at the same time so you request to buy the upgrades just as the cost value rises past the available amount of points. If done correctly, the yes-no prompt will calculate a negative amount of remaining points. Select yes and notice how your current points will loop around to an incorrect number. Return to the previous menu in order to refresh the point value, and it will now read 99999999 points.
After completing the game, start another game session and play the desert stages. One of them features a cinematic with Konig Monster Destroid and Zentradi enemies cheering a singing Loli-Chan idol. Afterwards, you will fight two Bosses with the Idoru occasionally appearing on the main screen. During the two Boss battles, try to bump into or shoot the allied Konig Monster that is in flying shuttle form. It will appear as a blue dot on the mini-map. Note: If you have two wingmen, the Monster shuttle is one of the three blue dots on the mini-map. Complete that mission to unlock the mech and its pilot.
