There is a secret Glitch Mode in this game! Here it is:
Note: This may wind up wiping your cartridge or game, but it hasn't happened to me not once yet, so try it any way, but be careful. Also, if the game freezes at any time after performing this code, then just restart the game. It won't mess up your game as far as I know.
1: Create a new Design Map. Fill it with NOTHING but plains. Then, starting in the top left hand corner of the sreen, fill it from left to right with Orange Star tanks, A-A's, Missiles, fighters, bombers, etc. in random order from left to right until the surplus is exhausted. Place only 15 units per row. There should be 3 rows of 15, then the last row should have 5. DO NOT GO OVER 15 PER ROW! Once you have 15 units in the first 3 rows, and 5 in the last, save this to any slot, with or withour a name, and then get out of this and go to Field Training.
2: Go to the Naval Forces mission. Follow all of Nell's instructions for Day 1. After she leaves you on that day, just end your turn. Olaf will move his units, and it will be your turn again. On Day 2, Nell will tell you something about the sub. Follow her instructions, and then she will leave again. Now, you know that T-Copter she wanted you to save on Day 1? Well, unload it from the Cruiser, and end your turn. Then Olaf will then attack a couple other units, then one of his curisers will attack the weakened T-Copter, and destroy it. Nell will come up saying you lost, and then you'll go back to the Firld Training select screen. Go back to Design Maps.
3: Back in Design Maps, load that Map you made earlier, and then, start destroying all of the units. Start at the top left hand corner, then go left to right, then begin on the next row, and go from right to left, and then, start on the 3rd row from left to right. You seem to skip some units, any how, after destroying about 3/4 of your army, nell will come up, and say that the orange Star Army has lost. *note: when destroying your troops, just hold down A and keep going* Now, just sit back and let the computer delete the rest.
4: Now, you can tell the game is screwed, seeing as how it seems both the Vs. mode and design maps are going at the same time. Now, this is a little tricky, but I'll try helping you here. Click A on an empty space, then try getting the cursor and hand near the End thing. A screen should come up saying Save, Yield, or Exit map. Try aligning the cursor and little hand back up with the Exit Map thing as...
