=>Stage Select: On the title screen, after Higgins gets bonked by the coconut, press R L R L A B A B.
=>Continue: In the first cave on the first island, walk just past the fifth skull and jump up and down to find the elevator to the secret room holding the Hudson Bee. When you die and return to the title screen, hold L and press START to continue with all of your collected items.
=> Debug Mode:
To start, you need a Game Genie, and Adventure Island 2. This is the code to use:
You'll start off in the "Scene Select" mode. This is basically a run-through of some various levels in the game. You can choose the scene number by pressing left or right. Be careful, as the higher you go, the better the chance of hitting a level that you get stuck at.
Pressing "B" on that screen switches you to the "World Select" mode, which is an alternate version of the level select. Just select numbers 01-08, and you're off.
Pressing "A" on either of those screens will move the cursor down an option called "DEBUG FL". If it's set on one or higher, it will make you invulnerable. Enemies don't hurt you, the time running out doesn't kill you, and bottomless pits exhibit a type of "wraparound" effect during gameplay.
Pressing "Select" will bring you to a new menu with some different options in them, as follows:
1. OBJ: This takes you to a mode to view all the game's sprites.
2. CHA: This is a graphics test.
3. SOUND: This is a sound test.
4. ENDING: This takes you directly to the ending.
5. STAFF: Takes you directly to the credits.
6. WARP: Takes you directly to the "Skip one level" secret room.
7. ITEM: Takes you directly to the "Hudson Bee" room, where you get a free continue.
8. ...: Does nothing.
It will also pay to have controller 2 plugged in, as when you have the Debug Mode in the game on, you can do the following:
Select: Game Freeze
Start: Free-Roaming Mode
(Use the control pad to move. The 0 represents you.)
"B" (Controller 2): Change dinosaur Higgins is riding.
"A" (Controller 2): Pallete-Editing mode
(This can only be done in Free-Roaming Mode)
