Hi I saw your question about "1-m sub circuit board." I'm guessing you're playing the game on VBA. The only way to beat the game is to delete all your save files and start over from the very beginning, but before you do that you need to go to Options-Emulator-Save type and check Flash, the go down to Flash 128k and select it. That should fix it. But remember to delete your save games and start over. It's a hassle, but it's the only way.
