Ys III: Wanderers from Ys Cheats

Press Select on Controller 1 to bring up the menu, then press Select on Controller 2 for a sound test.

Start a game and then save and exit.
You must have 2 controllers plugged in for this to work.

1) Turn the power on and wait until the logo screen appears (can't remember exactly what it is, but it is the one that fades in and out).

2) On the 2nd controller, when the logo gets through fading in (on mine, it fades in really white then gets a shade darker) and press Up, Down, Up, Down, Select, and Start before the logo fades out.

3) Continue with the game you started. While in the game, go to the status subscreen.

4) On controller 2 hit Select and you should see DEBUG pop up. If not, then you must try the code again. After DEBUG pops up you are invincible. Your health can go all the way back down, but after it gets past 1, it goes all the way back up.

Enjoy.

Turn on the game and wait for the Sammy logo to fade completely in. Then quickly enter this code on Controller 2: Up, Down, Up, Down, Select, Start. Start the game, and press Select to bring up the menu. Choose Status, then press Select on Controller 2. The word ''Debug'' will appear next to ''Status''. This will make you invincible and give you access to all areas on the world map.
